Ques. What are the priority topics for the BITSAT Biology subject?
Ans. The important topics asked in the BITSAT Biology exam are given below:
- Cell: Structure and Function
- Reproduction in Animals and Humans
- Genetics and Evolution
- Structure and Function of Plants and Animals
- Ecology and Environment
- Biotechnology and Its Applications
Ques. Which topics are considered “low-priority” but must not be ignored?
Ans. Some topics are rarely asked but can appear unexpectedly. For example:
| Subject | Topics |
|---|---|
| Physics | Units & Measurements, Experimental Physics |
| Math | Trigonometry, Set Theory & Relations |
| Chemistry | Some p-block & d-block elementsMole Concept basics |
Ques. Can I rely only on NCERT, and how many times should I revise each important topic?
Ans. Yes, for chemistry, NCERT is almost sufficient. For physics and math, NCERT provides concepts, but additional practice books or previous BITSAT papers are recommended for speed and variety:
| S.No. | Tips |
|---|---|
| 1 | High-weightage chapters: at least 3–4 revisions |
| 2 | Medium-weightage chapters: 2 revisions |
| 3 | Low-weightage chapters: 1 revision |
| 4 | Time yourself chapter-wise (e.g., 20–25 minutes for 20 questions). |
| 5 | Start slow to focus on accuracy. |
| 6 | Once accuracy is above 90%, work on reducing time per question gradually. |
Ques. Are there any chapters that students usually ignore but often appear in BITSAT?
Ans. Yes. Some topics from organic chemistry reactions, coordination compounds, vectors (math), and semiconductors (physics) are sometimes neglected, but appear in the exam. Don’t skip them completely.

Ques. Is BITSAT chapter-wise weightage the same for each paper set?
Ans. No, As each paper set of BITSAT is different, so, the weightage varies accordingly. However, weightage across sections is the same for each paper set. BITSAT official brochure states,
- Each student gets a unique set of questions
- Difficulty changes based on your performance.
- If you answer correctly, tougher questions appear next; if you answer wrong, easier ones follow.
“The questions will be selected at random from a large question bank. Different candidates will get different question sets. An expert committee will ensure that the question sets are of comparable difficulty level, content, question type, etc. In this matter, the decision of the expert committee will be final and binding on the candidate.”
