Practise 63 NEET previous year questions on Solutions, compiled from papers spanning 2002 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 NEET tests.

Solutions has been asked in 22 of the 39 years of NEET papers analysed (1988–2026), with 63 questions in all. 46% of them were easy, 33% moderate and 21% tough. Most of its questions came from 2019, with 5 questions that year. In the last three years (2024–2026) it had 11 questions across 13 papers, about 0.8 per paper.

The chapter's 4 topics are not weighted equally: Colligative Properties and Abnormal Molecular Masses (24 questions, 38%), Vapour pressure and raoult's law (24 questions, 38%), and Solubility and Concentration of Solutions (11 questions, 17%) have been asked the most. Colligative Properties and Abnormal Molecular Masses has also led over the last five years, with 4 questions.
