General Ability - General Science

Practise 1581 NDA previous year questions on General Science, compiled from papers spanning 2010 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 NDA tests.

General Science has been asked in 17 of the 21 years of NDA papers analysed (2006–2026), with 1581 questions in all. 78% of them were easy, 22% moderate and 0% tough. Most of its questions came from 2010, with 104 questions that year. In the last three years (2024–2026) it had 207 questions across 5 papers, about 41.4 per paper.

The chapter's 3 topics are not weighted equally: Physics (754 questions, 48%), Chemistry (505 questions, 32%), and Biology (322 questions, 20%) have been asked the most. Physics has also led over the last five years, with 196 questions. Physics has produced the most tough questions (3).
