Biology - Evolution
Practise 21 NEST (NISER) previous year questions on Evolution, compiled from papers spanning 2013 to 2026. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty NEST (NISER) tests.
Evolution has been asked in 11 of the 16 years of NEST (NISER) papers analysed (2011–2026), with 21 questions in all. 0% of them were easy, 86% moderate and 14% tough. Most of its questions came from 2023, with 4 questions that year. In the last three years (2024–2026) it had 6 questions across 4 papers, about 1.5 per paper.
The chapter's 2 topics are not weighted equally: Evidences of Evolution (18 questions, 86%) and Modern Theory of Evolution (3 questions, 14%) have been asked the most. Evidences of Evolution has also led over the last five years, with 11 questions. Evidences of Evolution has produced the most tough questions (3).
