Frequently Asked Questions

1.How many questions are in the NEST (NISER) 2024 Session 2 paper?

This paper has 80 questions in total - 20 each from Biology, Chemistry, Mathematics, and Physics.

2.Can I practise questions from just one subject?

Yes. Use the Biology, Chemistry, Mathematics, and Physics tabs at the top of the page to jump directly to that subject's question set within this paper.

3.Where can I find the Session 1 paper for the same year?

The NEST (NISER) 2024 Session 1 paper is listed separately - you can switch to it from the "NEST (NISER) Paper Wise PYQs" panel, under NEST (NISER) 2024.

4.What is the structure of the NEST (NISER) 2024 Session 2 paper?

The NEST (NISER) 2024 Session 2 paper on MARKS has 80 questions, organised by subject:

  • Biology: 20 questions - 20 single-correct.
  • Chemistry: 20 questions - 20 single-correct.
  • Mathematics: 20 questions - 20 single-correct.
  • Physics: 20 questions - 20 single-correct.
5.What is the difficulty level of the NEST (NISER) 2024 Session 2 paper?

Each question on MARKS carries a difficulty rating. Of the 80 rated questions in this paper, 5 (6%) are easy, 63 (79%) are medium and 12 (15%) are hard. Subject wise:

Open any question on this page. Its page shows the correct answer and, where one is available, the worked solution. A downloadable PDF of the whole paper is coming soon.

8.How should I use the NEST (NISER) 2024 Session 2 paper to check my preparation?

Set a timer, attempt the 80 questions as you would in the exam, and only then open the answers. Note which subjects and chapters cost you the most marks, and revise those first using the chapter-wise practice for NEST (NISER). Repeating this with other papers shows whether the same weak spots keep coming back.

9.Will the NEST (NISER) 2024 Session 2 paper help me prepare for NEST (NISER) 2027?

Yes. Every past paper shows the question styles and topics NEST (NISER) has asked before, and a solved paper gives you a realistic benchmark for speed and accuracy. Use it along with the other papers to spot the chapters that keep returning.
