Types of Questions in GATE Life Sciences 2025 Exam

There will be three types of questions – MCQ, MSQ, NAT.

Details of these types of questions is as follows –

Multiple Choice Questions (MCQ)

These questions carry or marks each. These questions will have a choice of four answers, out of which the candidate has to select (mark), the correct answer.

Multiple Select Questions (MSQ)

These carrying 1 or 2 marks each in all the papers and sections. These questions are objective in nature, and each will have choice of four answers, out of which ONE or MORE than ONE choice(s) are correct.

There is NO negative marking for a wrong answer for these questions. Also NO partial credit for choosing partially correct combinations of choices or any single wrong choice.

Numerical Answer Type (NAT) Questions

These questions carry or marks each. The answer is a signed real number for these questions, which needs to be entered by using the virtual numeric keypad on the monitor (computer’s keyboard will be disabled).

The answer can be an integer only such as 10 or -10. The answer may be in decimals as 10.1 or 10.01 or -10.001.

The candidates need to make an answer upto the said decimal point as instructed in question.

Appropriate range will be considered for numerical answer type questions so that the candidate is not penalized due to round-off errors.

It is better to give NAT answer up to three decimal places wherever required and possible.
