Defence GK Questions 2026

Static GK carries most of the General Knowledge marks in the defence exams, and science carries the largest share of it. In NDA & NA, Physics, Chemistry and General Science are about half of the 400 marks of Part B, and History, the freedom movement and Geography are about 20% each, as per the notice. In the CDS (II) 2026 General Knowledge paper, GK24 counted about 37 science questions, about 20 each on Polity and History, about 15 on Geography and environment and about 10 on the Economy; this count is guidance, not an official break-up.

Its GK list names history, culture and geography of India and its neighbours, the Constitution, inventions and discoveries, books and authors, and the Indian Armed Forces. This page holds GK24's topic-wise GK notes and GK questions tagged for NDA, CDS and Agniveer, in English and Hindi: General Science, Indian History, Art and Culture, Indian Polity, Geography, Indian Economy and Static GK.
