BITSAT Chapter-wise Weightage 2025 | Exam Prep Guide

Birla Institute of Technology and Science Admission Test (BITSAT) is an admission test conducted by Birla Institute of Technology and Science, or BITS. It is a privately deemed university with its main campus in Pilani, Rajasthan, and other campuses in Goa, Hyderabad, and Dubai. BITS is one of the top private technical institutes in India. BITS is ranked 20 in the list of all India engineering colleges by NIRF.

BITS conducts their own exam for admission in the various engineering courses. This exam is called BITSAT. Most of the students who appear for JEE Main also apply for BITS.

However, generally, students are confused regarding the exam pattern and chapter-wise weightage of BITSAT. In this blog, we’ll look at the chapter-wise weightage for BITSAT. This will help the aspirants to strategize their preparation in a more efficient way and hence maximize their chances of getting selected in BITS.

Birla Institute of Technology and Science Admission Test (BITSAT)

BITSAT is conducted in online mode in English. The exam syllabus of BITSAT is almost similar to JEE Main, but there are two extra subjects, reasoning and English, in it. Those who want to appear for B. Pharma select biology instead of mathematics.

There are a total 130 questions in BITSAT, out of which 30 questions are asked from Physics and Chemistry, 10 questions form English, 20 from reasoning, and 40 from mathematics/biology.

After attempting all 130 questions, candidates have the option to attempt 12 extra questions. These questions are from physics, chemistry, biology/mathematics, and reasoning. However once the candidate has opted for these extra questions, he/she cannot go back to the earlier attempted 130 questions for correction.

Candidates have 180 minutes to attempt the exam. However, there are no sectional timings for the exam.
