Are NEST PYQs sufficient to crack NISER Bhubaneswar?

Solving all official NEST Previous Year Questions from 2018 to 2025 chapter-wise is critical because NEST repeats structural problem styles, experimental conceptual models, and multi-concept calculus/organic chemistry applications. When paired with SciPrep's Smart Lessons and 180-mark mock tests, it provides complete preparation.

How many questions are in NEST each year?

In modern NEST exams (2020–2025), each subject section (Physics, Chemistry, Mathematics, Biology) contains 17 questions totaling 60 marks per section (240 marks total in the paper). Your final merit rank is evaluated out of 180 marks from your best three scoring subjects.

How can I solve NEST PYQs in chapter-wise CBT mode?

On SciPrep, every past year question from 2018 to 2025 is organized both year-wise and chapter-wise. You can launch instant CBT tests with a live timer, official marking schemes (+3/-1 single correct, +4/0 multi-correct), and instant AI diagnostic analytics.

Which chapters have the highest weightage in NEST Biology and Physics?

In Physics, high-weightage chapters include Rotational Motion, Wave Optics, Thermodynamics, and Electrodynamics. In Biology, Genetics & Molecular Biology, Cell Biology, Plant Physiology, and Ecology carry substantial marks and are crucial for clearing the Biology SMAS sectional cutoff.
