The General Ability Test (GAT) is the highest-scoring component of the NDA written exam, carrying 600 out of 900 marks. Success depends on mastering the 150-question paper, where each correct answer awards 4 marks. We at Exam Bhai emphasize that prioritizing English and current affairs is the smartest way to secure a competitive edge.
What is the Exam?
The National Defence Academy (NDA) examination is a prestigious, gateway-level entry process conducted by the Union Public Service Commission (UPSC) twice annually. It serves to recruit candidates for the Army, Navy, and Air Force wings of the NDA and the Indian Naval Academy Course (INAC). The selection process is divided into two major stages: a written examination consisting of Mathematics and the General Ability Test (GAT), followed by the rigorous Service Selection Board (SSB) Interview. Together, these stages evaluate a candidate's academic prowess, intellectual agility, and officer-like qualities (OLQs).

- English Mastery: This is the most scoring section. Dedicate at least one hour daily to reading newspapers and practicing grammar. Practice free mock tests for Defence on Exam Bhai to test your error-spotting speed.
- GK Strategy: Do not attempt to memorize everything. Focus on the high-weightage topics: Current Affairs (last 6 months), Physics, and Geography.
- Time Management: Since GAT has 150 questions, aim to complete the English section in 45 minutes, leaving ample time for the GK section.

Cut-Off Trends
According to historical data published on upsc.gov.in, the written exam cut-off typically ranges between 340 and 360 marks out of 900.
- Minimum Threshold: Candidates must secure at least 25% marks in each of the two papers to qualify for the merit list.
