Mathematics - Determinants
Practise 4 NEST (NISER) previous year questions on Determinants, compiled from papers spanning 2011 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.
Determinants has been asked in 4 of the 16 years of NEST (NISER) papers analysed (2011–2026), with 4 questions in all. 0% of them were easy, 100% moderate and 0% tough. Most of its questions came from 2026, with 1 question that year. In the last three years (2024–2026) it had 1 question across 4 papers, about 0.3 per paper.
The chapter's 3 topics are not weighted equally: Expansion of Determinants (2 questions, 50%), Adjoint and its Properties (1 question, 25%), and System of Linear Equations (1 question, 25%) have been asked the most. Over the last five years the most frequent topics have been System of Linear Equations (1).
