Every year after BITSAT, students rush back to their rooms and immediately start comparing notes — “Was your Physics easy?” “Did you get that weird Chemistry bonding question?” We at Phodu Club have been doing this for years now. We collect, verify, and analyze memory-based questions from students who sat across all sessions, and this year’s BITSAT 2026 questions from April 15 (Shift 1 and Shift 2) and April 16 (Shift 1 and Shift 2) gave us a LOT to talk about.
If you appeared in one of these slots, this article will help you benchmark your performance. If you’re appearing in upcoming slots, this is required reading. Also, based on previous year’s data, an average student improves by 20-80 marks in the April attempt compared to the January attempt. Therefore, don’t judge the final cutoffs based solely on the January attempt. And if you’re prepping for BITSAT 2027, this is exactly the kind of pattern data that will change how you study.
Let’s get into it.
BITSAT 2026 Memory-Based Questions: TL;DR
BITSAT 2026 memory-based questions from April 15 and 16 show a clear pattern: Physics leaned heavily on Rotational Mechanics, Units & Dimensions, and Thermodynamics. Chemical Kinetics, Organic Reactions, and Electrochemistry dominated chemistry. Mathematics covered Statistics, Integration, and Probability. Several questions were from deleted or out-of-syllabus topics, which caught many students off guard.

What the April 15 & 16 BITSAT 2026 Questions Tell Us About the Exam
Before we list every question, let us give you the big picture. At Phodu Club, we don’t just collect memory-based questions for fun. We study the pattern behind them.
Here is what stood out across all four sessions:
- Chemistry was the differentiator. Across all shifts, Chemistry had the highest number of questions that required conceptual depth. Scoring well in Chemistry this year separated the 340+ scorers from the 290 scorers.
- Several questions were from deleted or borderline topics. This is a problem we see every year with BITSAT. The syllabus officially aligns with Class 11 and 12 NCERT, but questions on topics like Semiconductors (Shift 2, April 15) and Agostic Interactions appeared, leaving students confused.
- Physics was calculation-heavy but concept-light. Most Physics questions were solvable with formulas if you knew the concept. No particularly abstract or tricky theory this year.
- Mathematics favored Statistics, Probability, and Calculus. Students who had skipped Statistics found themselves losing easy marks.
- English and Logical Reasoning remained straightforward but had a few vocabulary curveballs (more on that below).
Now, let’s break it all down session by session.
BITSAT 2026 April 15 — Shift 1: Memory-Based Questions
This was Session 1, Shift 1 of BITSAT 2026. Students reported a moderate level of difficulty. Here are the memory-based questions from each section.
Physics — April 15 Shift 1 (6 Questions)
| # | Topic | Question |
| 1 | Rotational Kinematics | A solid sphere rotating with angular velocity ω is dropped from a certain height. Find the time at which point P on the sphere comes to rest. |
| 2 | Centre of Mass | At what exact vertical height does the Centre of Mass (COM) of a uniform solid hemisphere lie? |
| 3 | Units & Dimensions | If a physical quantity X has the dimensions of velocity, express it in terms of electric field E and magnetic field B. (Answer: E/B) |
| 4 | SHM / Oscillations | If the time period of a 150g block is 10 seconds and another block has a time period of 20 seconds, find the mass of the second block. |
| 5 | Gravitation | The mass of a planet is 4 times that of Earth. If the weight of a body is the same on both planets, what is the ratio of their densities? |
| 6 | Newton’s Laws / Springs | Two blocks of mass M1 and M2 are on an inclined plane. A spring is attached to the bottom. If they move with velocities v1 and v2, find the ratio between v1 and v2. |
Our read: Shift 1 Physics was lighter in question count but covered the classic high-weightage chapters. COM of a hemisphere is a textbook result (3R/8 from the base). The Units & Dimensions question on E/B is a concept every serious BITSAT aspirant should know.
Chemistry — April 15 Shift 1 (12 Questions)
This was the most content-heavy section in Shift 1.
| # | Topic | Question |
| 1 | Chemical Kinetics | For reversible reaction A+2B⇌C, initial moles: A=1, B=1.5, volume=1L, equilibrium concentration of C=0.35M. Find Keq. |
| 2 | Biomolecules | What is the oxidation state of iron in deoxyhemoglobin/deoxymyoglobin? |
| 3 | S-Block | Which is the lightest metal? (Options: Li, Na, Ca, Mg) |
| 4 | Chemical Bonding | Identify the type of bonding/interaction — specifically referencing Agostic Interactions (distinguishing between 3c-4e and 3c-2e systems). |
| 5 | Salt Analysis | In identifying metal cations by salt analysis, which two core chemical concepts are majorly used? |
| 6 | Salt Analysis | If dilute H₂SO₄ (or dilute HCl) is used instead of concentrated H₂SO₄ with K₄[Fe(CN)₆], it releases toxic gases. Identify the gases. |
| 7 | Thermodynamics | For an isothermal system, determine the exact values of Work Done (W) and Change in Internal Energy (ΔU). |
| 8 | Thermodynamics | Evaluate efficiency using the Carnot engine formula: T1/(T1−T2) = Q/W. |
| 9 | Polymers | Calculate the Polydispersity Index (PDI) for given polymer data. |
| 10 | GOC / Stability | Compare the stability of C₂H₅⁺ and C₄H₉⁺ |
| 11 | Isomerism | Given Newman and Sawhorse projections of butan-2,3-diol derivatives with halogens, determine which compound is optically inactive. |
| 12 | Organic Reaction Mechanism | Nitrobenzene is subjected to CHCl3 and KOH with heat. Identify the major reacting intermediate that eventually yields a benzene ring with a −CHO group (Reimer-Tiemann on nitrobenzene context). |
Our read: The Agostic Interactions question (Q4) is a deep inorganic concept that many students, even well-prepared ones, would not have encountered. The PDI question in Polymers and the Reimer-Tiemann mechanism question were both above average difficulty. The isothermal thermodynamics question (Q7) is straightforward: ΔU=0, and W=nRT ln(V2/V1).
Mathematics — April 15 Shift 1 (7 Questions)
| # | Topic | Question |
| 1 | Statistics | Find the mean deviation about the mean for the first 100 natural numbers. |
| 2 | Properties of Triangles | Evaluate sinA·sinB·sinC in terms of semi-perimeter (s) and circumradius (R). |
| 3 | Properties of Triangles | Evaluate sin(B−C)·sin(B+C) in triangle ABC. |
| 4 | Indefinite Integration | Evaluate ∫x³(log x)³ dx. |
| 5 | Logarithms / Application | In a forest, trees increase by 10% every year. How many years for 100 trees to grow to 1000? (Note: Students reported a distractor option of 14.00000000001 in the choices.) |
| 6 | Probability | Given P(A∩B)=0.08 and P(A∩B∩C)=0.09, evaluate the conditional probability. (Note: This is a flawed question — the intersection of 3 sets cannot be larger than the intersection of 2.) |
| 7 | Coordinate Geometry (Parabola) | Find the coordinates of the focus for the given shifted parabola equation. |
Our read: Q6 on Probability was reportedly flawed — P(A∩B∩C) > P(A∩B) is mathematically impossible. Students who recognized this likely went with the option closest to a valid interpretation. The integration in Q4 requires repeated integration by parts — a time-consuming question. The forest/logarithm question (Q5) is straightforward: use log(10)/log(1.1) to get approximately 24.16 years.
English & Logical Reasoning — April 15 Shift 1 (6 Questions)
| # | Topic | Question |
| 1 | LR — Alphabet Series | Find the missing term: AB, CE, H_, __? (Options: A) MV B) KU C) KM D) KN) |
| 2 | English — Analogy | Embarrass : Humiliate :: ? : ? |
| 3 | English — Vocabulary | Find the correct synonym for “Occlude”. |
| 4 | English — Vocabulary | Find the correct synonym for “Compelling”. |
| 5 | LR — Data Sufficiency | Statement 1: A and B are brothers. Statement 2: B’s wife is X’s sister. Question: Who is the father of X? Determine if Statement 1, Statement 2, or both are sufficient. |
| 6 | LR — Sequencing | Lucas arrives before Cliff, Cliff arrives before Lucy, Lucy arrived before Tia. Who is 2nd to last? |
Our read: The alphabet series in Q1 uses a doubling gap pattern. “Occlude” means to block or obstruct. The sequencing question (Q6) gives the arrival order: Lucas → Cliff → Lucy → Tia. 2nd to last is Lucy.
BITSAT 2026 April 15 — Shift 2: Memory-Based Questions
Shift 2 on April 15 was significantly longer in terms of Physics. Students reported 25 Physics questions in their recall, making this the most Physics-heavy session across all four slots.
Physics — April 15 Shift 2 (25 Questions)
| # | Topic | Question |
| 1 | Thermodynamics / Heat Transfer | Room dimensions 5m×5m×3m, wall thickness 10cm. Room at 20°C, outside at 40°C. Find the power of AC required to maintain temperature. |
| 2 | Collisions / Energy | A disc of 5kg released from 300m height. Collides with a block of 120,000kg. All energy transferred to block. Find its velocity. |
| 3 | Kinetic Theory of Gases | Find the Vrms of a hydrogen molecule at 400K. |

| 7 | Semiconductors (Deleted Topic) | If temperature is increased, comment on ni (intrinsic) and ne (extrinsic) charge carriers. |
| 8 | Units & Dimensions | Angular impulse has the same dimensions as what? (Answer: ML²T⁻¹) |
| 9 | Units & Dimensions | Find the dimension of time in terms of G (Gravitational constant), R (Radius), and M (Mass). |
| 10 | Rotational Kinematics | A disc falling with acceleration g and constant angular velocity ω. Find the acceleration of the topmost point. |
| 11 | Rotational Kinematics | At what time will the acceleration of a specific left-side point on the falling rotating disc be zero? |
| 12 | EMI | A 1-meter rod is rotated in a magnetic field of 1T. Find the EMF induced. |
| 13 | Magnetic Effects of Current | Circular loop, 100 turns, radius 20cm. A proton passes through the center. Find the magnetic field/force. |
| 14 | Basic Electronics | Out of resistor, capacitor, and inductor, which can get electrically charged? (Answer: Capacitor) |
| 15 | Electrostatics | Square ABCD has charges q, q, −2q at A, B, C. Find the electric field at D. |
| 16 | Electrostatics | Three particles of mass M and charge q at vertices of equilateral triangle of side a. Find net potential at centroid. |
| 17 | Magnetism | A square of given side has clockwise current i. Find the magnetic field at the center. |
| 18 | System of Particles | Two spherical masses (charge q, mass m) tied with flexible inextensible string of mass M. Under what conditions is linear momentum conserved? |
| 19 | Newton’s Laws / Friction | Block on wedge at 30° incline, coefficient of friction = 0.5, at rest. Wedge accelerates to the right. Find the maximum acceleration of the block such that it doesn’t move relative to the wedge. |
| 20 | Magnetic Force | Magnetic field and velocity at 30°. A proton with given speed, mass, and charge. Find acceleration. |

| 23 | SHM / Waves | Wave marked on X-axis with readings. Find its equation. |
| 24 | Waves | y1=sin(3x−2t), y2=sin(3x−2t+π/3). Find the maximum velocity of the resultant wave. |
| 25 | Modern Physics (Particle Physics) | Pick the correct statement: A) both electron and photon are fermions B) electron is fermion, photon is boson C) electron is boson, photon is fermion D) both are bosons. (Answer: B) |
Our read: The Semiconductors question (Q7) is officially from a deleted portion of the NCERT syllabus for BITSAT. Students who had prepared for JEE Main would have been fine here, but students prepping exclusively from BITSAT resources may have skipped it. The dual rotational kinematics questions (Q10 and Q11) on a falling disc tested the same concept from two angles. The Wave Optics question (Q22) gives λ1/λ2 = 3, since the nth minima occurs at sinθ = nλ/a.
Chemistry — April 15 Shift 2 (14 Questions)
| # | Topic | Question |
| 1 | Periodic Table | What is the diagonal relationship element of Beryllium (Be)? (Answer: Al) |
| 2 | Electrochemistry | Find the molar conductivity of Ba(OH)₂ using Kohlrausch’s law. Data for NaOH and BaCl₂ are given. |
| 3 | Electrochemistry | Graphical question based on the molar conductivity graph from NCERT for weak electrolytes. |
| 4 | Chemical Kinetics | Numerical calculation based on the Arrhenius equation. |
| 5 | Chemical Kinetics | Standard calculation based on a first-order reaction. |
| 6 | Solutions | n-pentane and n-hexane with given molar mass, weight, and vapor pressure. Find the total pressure of the solution (Raoult’s law). |
| 7 | GOC (Solvent Effects) | Find the nucleophilicity order of F, Cl, Br, I in a polar aprotic solvent. (Note: A variation tested the order in polar protic medium.) |
| 8 | Organic Reactions | Compare acyl substitution rates between RCOCl, RCOOCH₃, RCONH₂, and RCOOH. |
| 9 | Organic Reactions | What is the product of the nitration of cumene? |
| 10 | Amines | Reaction of 3-aminobenzonitrile with SnCl2 and HCl (Stephen reduction). |
| 11 | Organic Reactions (Reagents) | NBS substitution followed by elimination using NaNH2. |

| 13 | Grignard Reagent | Multi-step reaction involving Grignard. Identify which specific step in the sequence was incorrect. |
| 14 | S-Block | Which of these metals reacts with Si? A) Na B) K C) Rb D) Cs. |
Our read: The nucleophilicity order question (Q7) is one students consistently get wrong. In polar aprotic solvents, nucleophilicity order is I > Br > Cl > F — the same as polarizability. In polar protic solvents, it reverses due to solvation. The Grignard multi-step image-based question (Q13) was reported as challenging because it required identifying an error in a sequence — a different type of question compared to a standard “find the product” question.
Mathematics — April 15 Shift 2 (6 Questions)
| # | Topic | Question |
| 1 | Indefinite Integration | Evaluate ∫(eˣ − 1) dx. |
| 2 | Permutation & Combination | A man travels from Goa to Hyderabad and returns such that he doesn’t use the same train. 25 trains available. How many ways are possible? |
| 3 | Quadratic / Polynomials | How many roots does t⁴+2t²−2=0 have in the range [0,1]? |
| 4 | Area Under Curve | Find the area between x²+y²=32 and y=x (in the first quadrant). |
| 5 | 3D Geometry | Lines/planes question — find the value of λ and select suitable options. |
| 6 | Quadratic Equations | If 4a+3b+3c=0, find the nature of roots of ax²+bx+c=0 in the interval [0,2]. |
Our read: The P&C question (Q2) is elegant: for the onward journey, 25 choices; for the return, 24 choices (cannot repeat the same train). Total = 25×24 = 600 ways. The polynomial roots question (Q3) requires either graphing or Descartes’ rule — a reasoning-based question, not just formula application.
English & Logical Reasoning — April 15 Shift 2 (4 Questions)
| # | Topic | Question |
| 1 | English — Vocabulary | Find the antonym of “Taciturnity”. (Answer: Loquacious) |
| 2 | LR — Number Series | 13, 27, 55, __, 223. Find the missing number. (Answer: 111; pattern is ×2+1) |
| 3 | LR — Alphabet Series | Find the missing terms in A, B, C, E, H, __, __ |
| 4 | LR — Odd One Out | Find the odd one out: Cliff, Sinkhole, and two other geological terms. |
Bonus Questions — April 15 Shift 2 (8 Questions)
These are the extra questions BITSAT offers if you complete the 130-question paper before time runs out. Attempting these is optional but can significantly boost your score.
| # | Section | Question |
| 1 | Maths | If a, b, c are in A.P. and tan⁻¹a, tan⁻¹b, tan⁻¹c are also in A.P., what can you say about a, b, c (none of them zero)? |
| 2 | Physics | If a test charge is placed on the surface of a conducting sphere, a non-conducting sphere with radius R, a disc of radius R, and a square of side R — which gets the most force? |
| 3 | Maths | A series with differences 18, 36, 72, 144, 288. Find the 288-difference term. |
| 4 | Physics | A box placed on a rotating disc gets pushed outwards by centrifugal force. What happens to its angular momentum? |
| 5 | Chemistry | Reaction of CHCl3 and Acetone with KOH produces what important medical compound? (Answer: Chloretone) |
| 6 | Maths | Given binomial trials n=5, p=2/3. Find E[(x/n − p)²]. (Answer: 2/45) |
| 7 | Physics | Find the dipole electric field at an equatorial point. |
| 8 | Chemistry | Convert a given Newman projection to a Sawhorse projection. |
Our read on bonus questions: We tell every student at Phodu Club — the bonus section is where your rank changes. If you can finish the main 130 questions with 10–12 minutes to spare, you have a shot at bonus questions. Even getting 2–3 bonus questions right can add 6–9 marks and potentially push you up by several rank positions. The Chloretone question (Q5 Bonus) and the binomial variance question (Q6 Bonus) were both doable for a well-prepared student.
BITSAT 2026 April 16 — Shift 1: Memory-Based Questions
April 16 Shift 1 is where BITSAT 2026 gave us the most talked-about question — the Virat Kohli cricket question in Physics.
Physics — April 16 Shift 1 (7 Questions)
| # | Topic | Question |
| 1 | Kinematics — The Virat Kohli Question | Virat Kohli drives the ball at 200 km/h when bowled at 160 km/h. Time of contact = 15ms, mass of ball = 150g. Calculate the force. |
| 2 | Work Energy Power | Mass = 2kg, Force = 3x+5, coefficient of kinetic friction = 0.2. Find Work done by force F in first 5 seconds if body starts from rest. |
| 3 | Units & Dimensions | W = ab²e^(r²/bKT). Find the dimension of a, where r is length, K is Boltzmann constant, T is temperature. |
| 4 | Rotational Mechanics | A disc and a ring of the same radius roll without slipping down an incline. Which takes more time? |
| 5 | Magnetic Effects of Current | Small length elements placed on a ring at equal lengths with current I. Given nL < 2πR, find the magnetic field at the center. |
| 6 | Gravitation / Satellites | A satellite dissipates energy. Find the value of energy when the orbit radius becomes half. |
| 7 | Thermodynamics | Adiabatic process question mixed with First Law of Thermodynamics (given q=u=500). |
Our read: The Virat Kohli question (Q1) is straightforward impulse-momentum: F = Δp/Δt = m(v2−v1)/t. The ball’s direction reverses, so you add the speeds: Δv = (200+160) km/h converted to m/s = 100 m/s, giving F = 0.15 × 100 / 0.015 = 1000N. The disc vs ring question (Q4) is classic: the ring has a higher moment of inertia (I=MR²) compared to the disc (I=MR²/2), so the disc reaches the bottom first. The ring takes more time.
Chemistry — April 16 Shift 1 (6 Questions)
| # | Topic | Question |
| 1 | Chemical Kinetics | Half-life of a reaction = 69.3 sec. Find the rate constant (s⁻¹). |
| 2 | Biomolecules (Out-of-Syllabus Trap) | Bromination oxidation of alpha/beta anomers and hydrolysis. Find the product. |
| 3 | Organic (Multi-Step) | Chlorobenzene reacted with Na/liquid NH₃ (Birch reduction), then with furan, followed by hydrolysis. Find the product. |
| 4 | Organic (Phthalic Acid) | Sequence of reactions starting from phthalic acid (likely Gabriel phthalimide synthesis). |
| 5 | Organic (Amines) | Nitration of amine — find the major product. |
| 6 | Stereochemistry | Identify the most stable conformation (Gauche/Eclipsed/Staggered) from given options. |
Our read: The half-life question (Q1) is a gift: 69.3 seconds was clearly chosen because ln2 ≈ 0.693, so k = 0.693/69.3 = 0.01 s⁻¹. The Birch reduction followed by a Diels-Alder reaction with Furan (Q3) is an advanced multi-step organic question that combines two reactions — this is the kind of question that separates 340+ scorers from the rest.
Mathematics — April 16 Shift 1 (9 Questions)
| # | Topic | Question |
| 1 | Statistics | Find Mean Deviation about the mean of 2, 4, 6. Also for 1, 3, 5…101. Data: 3, 4, 4, 7, 6, 10, 13, 19, 20, 21, 11 (Median=10). Find Mean Deviation about the median. |
| 2 | Probability | P(A)=1/3, P(B)=0. Find P(A |
| 3 | Probability (Distribution) | Probability distribution table given. Find P(X<6). (Given K=9/10, answer was 0.81.) |
| 4 | Functions | If 5f(x)+4f(1/x) = x−1, find f(1)+f'(1). |
| 5 | Limits | lim x→∞ ((x²+2x+2)/(x²+4x+2))ˣ |
| 6 | Determinants | Find the determinant of a 3×3 matrix where elements are (p+c, a, b), (c, p+a, b), (c, a, p+b). p is the perimeter; a, b, c are sides of the triangle. (Answer: 2p³) |
| 7 | Area Under Curve | Area bounded by x²+y=0 and x+y+2=0. |
| 8 | Coordinate Geometry (Orthocenter) | Vertices (v,1), (2,−2), (1,−2) with a given area. Find the orthocenter. (Answer: (6,2)) |
| 9 | Tangent / Normal | y=x³−3x²+2x. Tangent at x=1 cuts y-axis at A. Normal at x=1 cuts y-axis at B. Find distance AB. |
Our read: The P(A|B) question (Q2) is a conceptual trap. P(A|B) = P(A∩B)/P(B). Since P(B)=0, this is undefined. The correct answer is “Not Defined.” The determinant question (Q6) requires recognizing a special matrix structure — row operations give 2p³ cleanly. The limits question (Q5) can be solved by converting to the standard e limit form.
English & LR — April 16 Shift 1 (6 Questions)
| # | Topic | Question |
| 1 | LR — Math Puzzle | A person spends 1/3 on rent, 1/4 on food, 1/5 on transport, 1/7 on miscellaneous, and still has ₹1550 left. Find total salary. |
| 2 | LR — Syllogism | Statement 1: Women cannot vote. Statement 2: Some women are politicians. Assertion 1: All Males can vote. Assertion 2: Some politicians can vote. |

| 5 | LR — Data Sufficiency | Statement 1: A and B are brothers. Statement 2: B’s wife is X’s sister. Who is the father of X? |
| 6 | LR — Sequencing | Lucas arrives before Cliff, Cliff before Lucy, Lucy before Tia. Who is 2nd to last? |
Our read on Q1: 1/3 + 1/4 + 1/5 + 1/7 = 389/420. Remaining = 31/420 of salary = ₹1550. Total salary = ₹1550 × 420/31 = ₹21,000.
BITSAT 2026 April 16 — Shift 2: Memory-Based Questions
Physics — April 16 Shift 2 (10 Questions)
| # | Topic | Question |
| 1 | Astrophysics / Doppler Effect | A star from space shows a redshift. Is it moving away from or closer to the observer? (Answer: Moving away.) |
| 2 | Gravitation (Kepler’s Law Twist) | What would change in time period/orbit if gravitational force followed an inverse cube rule (F∝1/r³) instead of inverse square? |
| 3 | Gravitation | Earth is replaced by Mars. Mass of the sun is much bigger than Mars. Apply Kepler’s 3rd law — where would the sun’s position be? |
| 4 | Modern Physics (Photoelectric Effect) | Based on eVs = hν − Φ. If wavelength becomes 3 times original, what happens to stopping potential? |
| 5 | Modern Physics (De Broglie) | Find the De Broglie wavelength of an electron given V=900V. |
| 6 | Thermodynamics (Carnot Engine) | Flawed question — input/output temperatures given (misprinted as 310000K instead of 3100K) to find efficiency. |
| 7 | Rotational Mechanics | A hollow sphere and a solid sphere (same mass, same radii) roll down a rough inclined plane. Which reaches the bottom first? Compare kinetic energies. |
| 8 | Mechanics / Conservation | Pendulum with a weight displaced to height h. Identical block at ground. Find final velocities of both after collision. |
| 9 | Current Electricity (Theory) | Is current in a conductor influenced by drift velocity, thermal velocity, both, or neither? |
| 10 | Doppler Effect (Sound) | Change in frequency when sound is reflected off a stationary/moving wall. |
Our read: The Carnot question (Q6) had a misprint — students who noticed the unrealistic temperature and worked backward from options likely did fine. The hollow vs solid sphere question (Q7) is a standard result: solid sphere (I = 2MR²/5) reaches the bottom before the hollow sphere (I = 2MR²/3) because of lower rotational inertia. The De Broglie question (Q5): λ = h/√(2meV) — with V=900V, this gives a standard numerical result.
Chemistry — April 16 Shift 2 (10 Questions)
| # | Topic | Question |
| 1 | Quantum Chemistry (Advanced) | Evaluate ∫(−∞ to ∞) ψψ* dr. (Testing the normalization condition.) |
| 2 | Organic (Claisen Condensation) | Find the condensation product of 2-phenyl phenyl ethanoate with ethanol in potassium ethoxide solvent. |
| 3 | Organic (Reagents) | Chlorobenzene reacting with Na/liquid NH₃ (Birch reduction), then with furan, followed by hydrolysis. |
| 4 | Organic (Multi-Step) | A compound reacts with Br₂, then with neutral FeCl₃, and finally with NaHCO₃. Identify the compound. |
| 5 | Analytical Chemistry | Find the most suitable solvent for a mixture containing Anthracene and Sulphanilic acid. |
| 6 | Biomolecules (Trivia) | Identify the specific rotation angles of (+)-glucose and (−)-fructose. |
| 7 | Physical (Electrochemistry) | Find the solubility product (Ksp) of a sparingly soluble salt from given conductivities and molar conductance of ions. |
| 8 | Solid State | Find the density of a BCC/CCP lattice keeping the distance of the nearest ion constant. |
| 9 | Inorganic (P-Block) | Reaction of XeF₆ with an alkali. |
| 10 | Chemical Kinetics | Identify the correct graph plotting the rate of a first-order reaction versus concentration. |
Our read: The normalization condition question (Q1) tests whether students know ∫ψψ* dτ = 1 for a normalized wave function. The Ksp from conductivity question (Q7) follows the standard approach: molar conductivity Λm = κ × 1000/c, and once you have c (solubility), Ksp = c² for a 1:1 electrolyte. The XeF6 with alkali (Q9) tests P-block reactions — a topic many students underestimate.
Mathematics — April 16 Shift 2 (8 Questions)
| # | Topic | Question |
| 1 | Trigonometry | Given (sinα+cosα)²=0.89. Find which two regions on the graph α lies in. |
| 2 | Probability (Binomial) | A dice is thrown 4 times. Find the mean. |
| 3 | Calculus (Area) | Find the area between y=sinx and y=cosx above the x-axis from x=0 to x=π. |
| 4 | Differential Equations (Order) | An equation of an ellipse was given; find the order of its differential equation. |
| 5 | Statistics (Conceptual) | Mean of n terms is μ. One element μ was incorrect and removed. What happens to the new mean and variance? |

| 7 | Calculus (Integration Twist) | Evaluate x∫(0 to x) y(t)dt = (x+1)∫(0 to x) ty(t)dt to find y(t). |
| 8 | Coordinate Geometry (Parabola) | Find the distance between focus and directrix for y²=8x. |
Our read: The parabola question (Q8) is a gift. For y²=8x, 4a=8 so a=2. Distance between focus and directrix = 2a = 4. The ellipse differential equation (Q4): standard form has 2 constants (a and b), so order of the differential equation is 2. The area between sinx and cosx (Q3) from 0 to π: they intersect at π/4. Area = 2√2 − 2.
English & LR — April 16 Shift 2 (5 Questions)
| # | Topic | Question |
| 1 | English — Vocabulary | What is the term for a person who kills his own sister? (Answer: Sororicide.) |
| 2 | English — Spelling | Identify the correct spelling of “Meticulously”. |
| 3 | LR — Syllogism | “A is good to B, B is good to C, therefore A is good to C.” Is this a valid transitive argument? |
| 4 | LR — Matrix Decoding | Two matrices given. Decode the sequence for words like “COLD” and “RISK”. |
| 5 | LR — Alphabet Series | Predict the next term with a +4 jump after each letter. |
Pattern Analysis: What BITSAT 2026 Questions Reveal About Preparation
Now that you have all the questions, here is what we at Phodu Club want you to actually do with this information.
Topic Frequency Across All 4 Sessions
| Subject | Most Repeated Topics |
| Physics | Rotational Mechanics, Units & Dimensions, Thermodynamics, Modern Physics, Electrostatics |
| Chemistry | Chemical Kinetics, Electrochemistry, Organic Reaction Mechanisms, Stereochemistry, Thermodynamics |
| Mathematics | Statistics, Probability, Calculus (Area & Integration), Coordinate Geometry, Properties of Triangles |
| English & LR | Alphabet Series, Number Series, Vocabulary Synonyms/Antonyms, Data Sufficiency, Sequencing |
Questions That Appeared in Multiple Sessions
This is something we pay close attention to at Phodu Club. Certain questions appeared across multiple slots with identical or near-identical wording:
- Data Sufficiency — A and B are brothers, B’s wife is X’s sister: Appeared in April 15 Shift 1, April 16 Shift 1, and April 16 Shift 2.
- Sequencing — Lucas, Cliff, Lucy, Tia arrival order: Appeared in April 15 Shift 1 and April 16 Shift 1.
- Birch reduction of Chlorobenzene + Furan + Hydrolysis: Appeared in both April 16 Shift 1 and Shift 2.
- Rotational Mechanics — Hollow vs Solid sphere on incline: Similar questions appeared across multiple sessions.
This tells you something important: if you’re appearing in a later slot, pay attention to what earlier slot students report. The concepts repeat even when exact numbers change.
What Students Got Wrong — The Common Mistakes We See
We get this pattern again and again. Students who prepared for JEE Main but didn’t specifically prepare for BITSAT 2026 questions lost marks in three places:
- English & LR. JEE aspirants often completely skip this section. But English & LR is 25 questions in BITSAT — that is nearly 20% of the total paper. Students who score 20/25 here with a week’s dedicated prep are at a massive advantage.
- Bonus Questions. Students who finished the paper with time to spare didn’t attempt bonus questions because they were tired or unsure. Every bonus question attempted correctly adds 3 marks. Even 4–5 correct bonus answers can push your score by 12–15 marks.
- Deleted Topic Questions. BITSAT sometimes includes topics that have been removed from the NCERT syllabus (like Semiconductors in Shift 2, April 15). Students who still know these topics have an edge. We always tell students at Phodu Club — don’t completely drop topics from your preparation just because they’re officially “deleted.”
How to Use These BITSAT 2026 Questions in Your Prep
If you’re appearing in future BITSAT 2026 slots or preparing for the next cycle, here is what to do with this question list:
- Go topic by topic, not question by question. Don’t just read the questions. Find every topic listed in the tables above and test yourself on it.
- Solve the questions you couldn’t answer. Write down the ones you didn’t know how to approach and work through them fully.
- Time yourself. BITSAT gives you 3 hours for 130 questions. That’s roughly 82 seconds per question. Practice under timed conditions.
- Look at what was repeated across shifts. Data Sufficiency, Alphabet Series, Kinematics, and Chemical Kinetics all appeared in multiple sessions. These are near-certain bets.
For structured practice with papers built around exactly these patterns, check out the BITSAT Test Series on Phodu Club. We’ve built our mocks to reflect the difficulty and topic distribution we’ve analyzed from papers exactly like these.
You can also check our detailed write-ups on BITSAT important chapters and BITSAT exam pattern and cutoff to cross-reference these questions with what matters most for your score.
For students still figuring out resources, our BITSAT preparation guide and BITSAT previous year papers analysis are worth reading before your exam date.
If you want to understand where you stand on the scoring side, our posts on BITSAT marks vs rank and BITSAT cutoffs will help you set realistic targets. And if you’re prepping from books, check what our BITSAT preparation books analysis recommends.
One More Thing: How to Actually Study From Memory-Based Questions
We built Phodu Club because we saw students collect memory-based questions and then do nothing useful with them. They’d read the list, feel good about the ones they recognized, and move on. That is the wrong approach.
Here is what we recommend:
- Take every question you couldn’t answer. Mark it. That is your personal weak area list for BITSAT 2026.
- Find the concept behind the question, not just the answer. The Virat Kohli question is about impulse. The diagonal relationship question is about periodic trends. Understand the concept so you can handle any variation.
- Do one timed mock every 3 days. After studying memory-based topics, take a full-length mock to test if you’ve actually internalized them. Our BITSAT crash course is built around exactly this kind of feedback loop.
- Don’t ignore English. One week of focused vocabulary and LR practice is often worth 15–20 extra marks. Check our BITSAT English preparation guide for a structured approach.
- Attempt bonus questions. Practice finishing 130 questions in 2.5 hours so you have buffer time for bonus attempts.
We’ve seen this pattern again and again — students who have a plan for the bonus section and English & LR consistently outperform students who are technically stronger but treat those sections as afterthoughts.
Frequently Asked Questions (FAQ)
1. Are BITSAT 2026 memory-based questions accurate?
Students recall memory-based questions immediately after the exam. They are not 100% verbatim since BITSAT prohibits cameras or note-taking inside the hall. The questions and concepts are directionally accurate, but the exact wording may differ from what appeared on screen.
2. How many questions were from deleted or out-of-syllabus topics in BITSAT 2026?
Based on what students reported across all four sessions, at least 2–3 questions per session touched on topics that are either deleted from the current NCERT syllabus (like Semiconductors) or from advanced inorganic chemistry (like Agostic Interactions). BITSAT’s syllabus alignment with NCERT is not always exact.
3. Which subject was toughest across BITSAT 2026 April 15 and 16 sessions?
Chemistry was consistently reported as the most challenging across all four sessions. Organic reaction mechanisms, stereochemistry, and advanced physical chemistry questions were the primary difficulty drivers.
4. Were bonus questions easy or hard in BITSAT 2026?
The bonus questions from April 15 Shift 2 included both straightforward (Chloretone product, dipole field) and moderately hard (binomial variance, angular momentum) questions. If you can complete the main 130 questions in under 2.5 hours, you should always attempt bonus questions.
5. How many questions were repeated across different BITSAT 2026 sessions?
At least 2–3 questions appeared in identical or very similar form across multiple sessions. The Data Sufficiency question (A and B are brothers, B’s wife is X’s sister) appeared word-for-word in April 15 Shift 1, April 16 Shift 1, and April 16 Shift 2. The sequencing question about Lucas, Cliff, Lucy, and Tia also appeared in multiple sessions.
6. What is the expected BITSAT 2026 cutoff based on this paper analysis?
We are not in a position to confirm cutoffs until official data is released. Based on paper difficulty analysis, our read is that the April 15 and 16 sessions were moderate in difficulty overall. For historical reference, check our BITSAT 2025 cutoffs post and our write-up on why BITSAT cutoffs dropped in 2025.
7. Should I study from memory-based questions for future BITSAT sessions?
Yes, absolutely. Memory-based questions reveal the actual exam pattern better than any coaching material. But don’t just read them — solve the underlying concept for every question you couldn’t answer. That is the only way this list helps you.
8. How does Phodu Club help students appearing in upcoming BITSAT slots?
At Phodu Club, we take exactly this kind of question-level analysis and convert it into a targeted preparation plan. Our BITSAT Test Series is updated to reflect actual exam patterns, and our BITSAT Crash Course is built for students who need to sharpen quickly. We’ve worked with students across all score ranges, and our approach focuses on fixing the specific gaps that are actually costing marks — not just solving more and more questions without direction.
