Chemistry - Solid State
Practise 10 NEST (NISER) previous year questions on Solid State, compiled from papers spanning 2011 to 2023. 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.
Solid State has been asked in 9 of the 16 years of NEST (NISER) papers analysed (2011–2026), with 10 questions in all. 40% of them were easy, 60% moderate and 0% tough. Most of its questions came from 2019, with 2 questions that year. In the last three years (2024–2026) it had 0 questions across 4 papers, about 0 per paper.
The chapter's 4 topics are not weighted equally: Cubic system (6 questions, 60%), Stoichiometric defects (2 questions, 20%), and Ionic structure (1 question, 10%) have been asked the most. Cubic system has also led over the last five years, with 1 question.
