BITSAT Exam Pattern & Marking Scheme
BITSAT 2025 will be an online computer-based test. It is designed to check the student’s knowledge in Physics, Chemistry, Mathematics or Biology, English Proficiency, and Logical Reasoning. The total duration of the exam is 3 hours (180 minutes) without any break.
The BITSAT-2025 exam is divided into four parts:
| Part | Subject | Number of Questions |
| Part I | Physics | 30 |
| Part II | Chemistry | 30 |
| Part III (a) | English Proficiency | 10 |
| Part III (b) | Logical Reasoning | 20 |
| Part IV | Mathematics (or Biology)* | 40 |
| Total | — | 130 |
- Candidates applying for B.Pharm or B.E. Environmental and Sustainability Engineering can choose Biology instead of Mathematics in Part IV.
- All questions are multiple choice with four options. Only one option is correct.
- Each correct answer gets +3 marks.
- Each wrong answer results in -1 mark.
- Unattempted questions get 0 marks.
Navigation and Flexibility
- Candidates can move freely between questions.
- There is no time limit for any individual section.
- You can skip questions and return to them later.
- However, you cannot select more than one option per question.
Extra Questions Option: BITSAT has a special feature for top-performing students. If a student answers all the 130 questions and still has time left, the system unlocks 12 extra questions. These questions are:
- 3 from Physics
- 3 from Chemistry
- 3 from Mathematics or Biology
- 3 from Logical Reasoning
That means you can answer up to 142 questions if you attempt all 130 questions first. But keep in mind:
- Once you choose to attempt these 12 extra questions, you cannot go back to change any of your previous answers from the 130 questions.
- These extra questions are optional. Attempt them only if you are confident.
Level of Difficulty: The paper is designed in such a way that a well-prepared student can attempt all 130 questions in 3 hours. However, not all students may be able to do so, especially due to the pressure of speed and accuracy.
The questions are selected randomly from a large question bank. Each student gets a unique set of questions. All sets are made equal in terms of difficulty, question types, and content.
Language and Tools Allowed
- The test will be in English only.
- No calculators or logarithmic tables are allowed.
- Scratch pads will be provided for rough work.
- You must carry a pen for signing and rough work.
- Mobile phones, smartwatches, and personal belongings are strictly prohibited.
