About this paper

This is a memory-based recollection of the Indian Air Force Airmen Group X exam held on 6 November 2020, not an official question paper. Its 70 multiple-choice questions run 1–20 English, 21–45 Physics and 46–70 Mathematics, and an answer key with the correct option for each question follows. The English part begins with a passage about two students sent by their Guru to fetch dry leaves that nobody uses, then covers voice, narration, spelling, one-word substitution, idioms and sentence rearrangement. Physics includes magnetism, surface tension, capacitors, semiconductors and thermodynamics; Maths includes calculus, statistics, progressions, trigonometry, probability and conic sections. No marks or time limit are printed.
