What is the BITSAT Biology Exam Pattern Marking Scheme?

In the BITSAT Biology exam pattern 2025, you will face 40 questions out of the total 130 in the biology section. Each correct answer is worth +3 marks, and each wrong answer deducts 1 mark (-1).

There are no marks for unanswered questions. For example, 40 MCQs × 3 marks = 120 marks available in Biology. This is important to keep in mind as you attempt each question; a correct choice adds three points, but a wrong guess costs one point.

How Does Negative Marking Work in the Biology Section?

If you answer a question incorrectly, 1 mark is subtracted from your score. However, you are not penalised for skipping a question (those give 0 marks). In other words, 1 mark for every wrong answer and 0 for unattempted.

This means you should avoid wild guessing; it's better to leave a question blank than risk losing a mark on a pure guess.

In practice, this means if you complete your 40 Biology questions and still have time, you get up to 3 more Biology questions among the bonus ones. Attempting these can boost your score
