Frequently Asked Questions

1.How many questions are in the NEET 2021 paper?

This paper has 200 questions in total - 44 from Botany, 50 from Chemistry, 50 from Physics, and 56 from Zoology.

2.Can I practise questions from just one subject?

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

3.How is the NEET 2021 paper structured?

The NEET 2021 paper on MARKS has 200 questions, organised by subject:

  • Botany: 44 questions - 44 single-correct.
  • Chemistry: 50 questions - 50 single-correct.
  • Physics: 50 questions - 50 single-correct.
  • Zoology: 56 questions - 56 single-correct.
4.How difficult is the NEET 2021 paper?

Each question on MARKS carries a difficulty rating. Of the 200 rated questions in this paper, 122 (61%) are easy, 55 (28%) are medium and 23 (12%) are hard. Subject wise:

  • Botany: 32 easy, 11 medium, 1 hard
  • Chemistry: 22 easy, 18 medium, 10 hard
  • Physics: 25 easy, 15 medium, 10 hard
  • Zoology: 43 easy, 11 medium, 2 hard
5.Which chapters were asked the most in the NEET 2021 paper?

The chapters with the most questions in each subject were:

  • Botany: Cell Cycle and Cell Division (5), Plant Kingdom (5), and Animal Kingdom (4).
  • Chemistry: Chemical Bonding and Molecular Structure (4), Hydrocarbons (4), and General Organic Chemistry (3).
  • Physics: Current Electricity (4), Electrostatics (4), and Magnetic Effects of Current (4).
  • Zoology: Molecular Basis of Inheritance (9), Biotechnology - Principles and Processes (7), and Biotechnology and Its Applications (5).
6.Are there any out-of-syllabus questions in the NEET 2021 paper?

Yes. 37 of the 200 questions in this paper are marked on MARKS as outside the current syllabus. You can still practise them for the concept, but they are a lower priority if you are short on time.

7.Where can I find the solutions for the NEET 2021 paper?

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 NEET 2021 paper to check my preparation?

Set a timer, attempt the 200 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 NEET. Repeating this with other papers shows whether the same weak spots keep coming back.

9.Will the NEET 2021 paper help me prepare for NEET 2027?

Yes. Every past paper shows the question styles and topics NEET 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.
