• The question paper of NEST 2026 will be based on Physics, Chemistry, Biology, and Maths topics from the Class 11 and Class 12 NCERT syllabus.

• It will contain objective-type questions that must be solved within 3 hours.

• There will be 20 questions from each subject (PCMB) in the question paper, making the total number of questions 80.

How to Prepare for NEST 2026 in 15 Days?

To prepare for NEST 2026 in 15 days, candidates must follow a focused plan rigorously. Emphasise the most effective strategies and avoid methods that waste time.

The complete preparation plan is mentioned below:

Day 1-8: Learn and Revise High-Weightage Topics

• To start NEST 2026 preparation, candidates must start clearing concepts related to the high-weightage topics in the NEST 2026 syllabus. The syllabus is based on NCERT’s Classes 11 and 12 for PCMB.

• The most important topics for Physics, Chemistry, Maths, and Biology are Modern Physics (Dual Nature of Radiation and Matter, Atoms and Nuclei), Aldehydes, Ketones & Carboxylic Acids, Quadratic Equations & Complex Numbers, and Plant Physiology, respectively.

• Download the PDF provided below to check all the most important topics for NEST 2026. These topics have been identified after reviewing NEST's previous year s’ question papers from 2017 to 2024.

• Once you know all the important topics, make notes of them and revise them.

• Do not spend your time learning low-weightage topics.

Revise NEST 2026 Topics With SciAstra

To help you revise PCMB topics for NEST 2026, SciAstra will conduct online sessions called "Maharevision".

The first session will be live on May 26, 2026, on the official SciAstra YouTube channel.

The link to access the SciAstra Maharevision sessions will be provided below.

Day 9-12: Solve NEST Previous Years’ Question Papers

• Many NEST questions are repeated from previous years’ papers; therefore, the best resource to prepare in 15 days is to practise PYQs.

• To access all NEST PYQs in one place, with detailed video solutions for each question, refer to the SciAstra NEST PYQ Book (2018-2025).

• The details about the book are mentioned below:

Day 13-15: Take NEST Mock Tests

Mock tests for NEST or any other entrance exam are the best resource, as they help you understand the types of questions asked and the overall structure of the question paper.

Therefore, to prepare for NEST, you must take mock tests.

If you do not know where to get the best mock tests, check out SciAstra’s IAT & NEST 2026 Crash Course available for IAT, NEST, and IAT + NEST (Combo). The crash course includes mock tests for IAT and NEST.

It includes the following features:

• Live revision sessions (Mon–Sat)

• 12 IAT Mock Tests

• 12 NEST Mock Test

• IAT & NEST PYQs (2018–2025)

• Daily problem-solving sessions (8 PM–10 PM)

• Personalised mentorship (only for the personalised crash-course batch)

The SciAstra IAT & NEST crash courses are available in two languages: Hinglish and English. Check out the links below.

Note: The SciAstra IAT & NEST 2026 crash course is valid until IAT 2026 (June 7, 2026) and NEST 2026 (June 6, 2026).

Conclusion

Preparing for NEST 2026 in 15 days may seem challenging, but with smart planning and focused preparation, you can still achieve a good score. The key is to avoid wasting time on less important topics and instead focus on high-weightage chapters, regular revision, PYQs, and mock tests.

Remember that consistency matters more than studying for long hours without direction. Revise concepts daily, analyse your mistakes, and improve your speed and accuracy through practice tests. Even small improvements each day can make a significant difference in the final exam.

Most importantly, stay confident and avoid panic during the last few days of preparation. Trust your preparation, follow a disciplined routine, and use quality resources like revision sessions, PYQ books, and mock tests to maximise your performance in NEST 2026.
