General Knowledge for NDA

GAT Part B's General Knowledge is 100 questions across six subjects, and it stays close to CBSE Class 9-10 level rather than undergraduate depth — recall speed, not derivation, decides this section. Physics is the heaviest single subject at 25%, covering measurement, mechanics, heat, light, sound, and electricity & magnetism, plus everyday and defence applications like RADAR, SONAR and satellites — nothing here is computational, so it is pure recall. Geography and History & Freedom Movement are tied at 20% each: Geography spans physical geography (solar system, landforms, climate), Indian geography and world geography, while History leans heavily on the 1857–1947 Freedom Struggle, which alone typically accounts for more than half of that chapter's questions and rewards clean fact-to-year and person-to-event matching. Chemistry (15%) mirrors Physics in staying at CBSE 9-10 level — matter, atomic structure, the periodic table, bonding, chemical reactions, and acids/bases/salts. General Science (10%) mops up biology, the human body, nutrition and common diseases, and scientific instruments and discoveries, while Current Events (10%) is the only sub-area without a fixed, once-and-done syllabus — it needs a running habit of reading current affairs in the months before the exam rather than a single revision pass.
