The Joint Entrance Examination (JEE) Mains is a highly competitive exam, taken by hundreds of thousands of students across India each year, and is the first step for aspirants aiming to secure seats in prestigious engineering colleges such as the National Institutes of Technology (NITs), Indian Institutes of Information Technology (IIITs), and other Government-Funded Technical Institutes (GFTIs). A critical element of this examination is understanding the percentile system, as it plays a significant role in ranking candidates and determining their admission eligibility. In this article, we will thoroughly discuss the percentile system, interpret what scoring 120 marks means in terms of percentile, analyse admission possibilities, and finally, provide strategic recommendations for students aiming to improve their percentile from this score benchmark.
Percentile System in JEE Mains
Percentile vs. Absolute Score
In competitive exams like JEE Mains, understanding percentile is crucial for candidates to gauge their performance and see how they stand in relation to other students. Let’s clarify the difference between the absolute score and the percentile score, as this is often a source of confusion for candidates and parents alike.
- Definition of Percentile: Unlike an absolute score, which simply indicates the total marks out of 300 that a candidate has earned, the percentile is a relative measure. It reflects a candidate’s standing among the pool of examinees. For example, a percentile score of 90 means the candidate has scored higher than 90% of the candidates in that specific exam session.
- Calculation of Percentile: The percentile score in JEE Mains is calculated based on the number of students who scored less than or equal to a particular candidate’s score in their respective session.
- Here’s the basic formula for calculating percentile:
Percentile=(Number of candidates with marks ≤ candidate’s score/Total number of candidates)×100
For instance, if a candidate’s score places them above 80% of the students in their shift, they receive an 80th percentile. Percentile rankings are a means of comparing performance across the entire range of test-takers rather than an absolute score which simply indicates the number of correct responses.
Importance of Percentile in Large Exams: The JEE Mains exam is conducted across multiple days and shifts due to the large number of applicants, which makes percentile ranking essential for fair comparison. Percentiles normalise performance so that students in different shifts with varying levels of exam difficulty can still be fairly ranked against each other.
How Percentile Varies Across Exam Shifts
The JEE Mains exam is conducted in multiple shifts over several days, with different sets of question papers for each shift. Since some shifts may have slightly easier or harder papers than others, percentile ranking accounts for this variability.
- Different Exam Sessions and Normalisation: Each exam session may see a unique distribution of scores based on question paper difficulty and student preparation levels. To address this, the National Testing Agency (NTA) applies normalisation across different sessions. This ensures that candidates’ scores can be fairly compared even if the difficulty of papers varies across sessions. By using statistical methods, normalisation adjusts scores to account for these differences, providing an equivalent percentile ranking for students in different shifts.
- Role of Normalisation in Creating Fairness: Without normalisation, students who encounter a more challenging question paper in their shift would be unfairly disadvantaged. Normalisation, thus, levels the playing field, ensuring that the percentile score reflects a candidate’s performance in a way that accounts for question paper variations. This process is essential in large-scale exams like JEE Mains, where a large pool of students competes in various sessions.
JEE Main Expected Percentile for Scoring 120 Marks
Approximate Percentile for 120 Marks
For students scoring around 120 marks in JEE Mains, understanding their likely percentile range is important for assessing college admission opportunities. Percentile scores vary each year due to factors like the overall difficulty level of the exam and the collective performance of students.
Expected Percentile Range: Based on trends from previous years, a score of 120 generally corresponds to a percentile between 93 and 96. This range suggests that the candidate has performed better than approximately 93-96% of students who took the exam in the same shift. However, this percentile range is an estimate, as it can fluctuate based on annual variations in question paper difficulty and student performance distribution.
Analysis Based on Previous Years’ Data
Historical data from past JEE Mains exams indicate that scores in the range of 120 marks have consistently placed candidates within the 93-96 percentile range. However, slight variations in difficulty level, number of test-takers, and performance trends each year can lead to minor fluctuations in this percentile range.

Factors Affecting Percentile for 120 Marks
Various factors influence the exact percentile associated with a score of 120 marks. These factors include the difficulty of the specific exam shift, the number of students taking that shift, and the average scores observed within the session.
- Difficulty of the Specific Exam Shift: Each JEE Mains shift may have a different level of difficulty. If the shift is relatively challenging, a score of 120 might correspond to a higher percentile compared to an easier shift. This is because students in tougher shifts generally achieve lower average scores.
- Number of Students Taking the Shift: The percentile score is also influenced by the number of candidates appearing in a particular session. In shifts with more students, a score of 120 might yield a slightly different percentile compared to shifts with fewer participants.
- Variations in Average Scores per Session: Shifts with higher average scores can impact the percentile calculation, as a candidate’s score is compared to those around them. For example, a score of 120 in a shift with an exceptionally high average may yield a lower percentile compared to shifts where the average is lower.
Competitiveness of Scoring 120 Marks for College Admissions
Admission in NITs, IIITs, and GFTIs
Scoring 120 marks can provide candidates with a range of opportunities in NITs, IIITs, and GFTIs, though the most competitive branches may remain out of reach.
Chances of Securing a Seat in Certain Branches: With a percentile between 93 and 96, candidates stand a fair chance of admission in some branches at NITs, IIITs, and GFTIs. However, high-demand branches like Computer Science and Electronics are likely to have higher cutoff scores, requiring a higher percentile than what 120 marks typically yields.
Preferred Branches and Less Competitive Options: Candidates scoring around 120 may need to consider branches with lower competition, such as Civil, Chemical, or Metallurgical Engineering. These branches tend to have slightly lower cutoffs, making them accessible at a percentile between 93 and 96. Candidates interested in emerging fields or interdisciplinary branches might also find opportunities in niche areas where competition is relatively low.
State Quotas and Reservation Impact
The category under which a candidate applies significantly affects their chances of admission. Additionally, each NIT reserves a portion of seats for candidates from the same state, which can lower the required cutoff for local students.
- Benefits for State and Reserved Category Candidates: Many NITs and GFTIs have seat reservations for local candidates. This can result in lower cutoffs for state candidates compared to all-India candidates. Similarly, candidates from reserved categories (SC, ST, OBC, EWS) have lower cutoff requirements, which can greatly enhance their chances of admission.
- Influence of State Quotas on Cutoffs: State quotas impact the admission process by providing home state candidates with slightly relaxed cutoffs. This can be beneficial for candidates scoring around 120 marks, as they may still secure admission to an NIT within their home state.
