Part A: English (200 Marks): Syllabus covers understanding English and use of words, including Grammar and usage, vocabulary (synonyms, antonyms), comprehensions, and cohesive devices (ordering of words/sentences).
Part B: General Knowledge (400 Marks): The GK paper covers a vast landscape. The approximate weightage is usually: Physics (25%), Chemistry (15%), General Science (10%), Social Studies/History (20%), Geography (20%), and Current Affairs (10%).
5. Intelligence & Personality Test (SSB Interview)
Candidates who clear the written cut-off are called for the Service Selection Board (SSB) Interview. This is a 5-day process designed to assess the presence of 'Officer Like Qualities' (OLQs). The SSB interview carries 900 Marks, equal weightage to the written exam.

6. Expert Preparation Strategy for NDA 2026
Mathematics is Key: Paper-I is the first hurdle. If you do not qualify in Mathematics, Paper-II will not even be evaluated. Focus heavily on NCERT solutions for classes 11th and 12th.
Current Affairs for GAT: While History and Geography are vast, Current Affairs is highly scoring. Read daily news focusing on national events, defense technologies, international summits, sports, and awards from the last 6–9 months.
English Practice: Work on daily reading habits (newspapers) to naturalize vocabulary. Practicing Antonyms, Synonyms, and Idioms is essential.
Physical Fitness Starts Now: The medical standards for the Armed Forces are uncompromising. Start basic running, push-ups, and a structured exercise routine early. Do not wait for the written results.
