Starting NDA preparation immediately after 10th grade involves building a rock-solid foundation in Mathematics and English while developing officer-like qualities. Candidates must focus on NCERT books, master time management, and maintain physical fitness. Early preparation allows you to clear the UPSC NDA exam on your first attempt after class 12th.
What is the Exam?
The National Defence Academy (NDA) examination is the gateway to becoming a commissioned officer in the Indian Army, Navy, and Air Force. Conducted biannually by the Union Public Service Commission (UPSC), the exam is designed to test a candidate's academic aptitude, general awareness, and psychological fitness. After clearing the written exam and the rigorous Services Selection Board (SSB) interview, successful candidates undergo training at the NDA in Khadakwasla, Pune. We at Exam Bhai view this not just as an exam, but as a commitment to national service.

- Maths is King: Dedicate at least 2 hours daily to Mathematics. Practice speed calculations and shortcuts.

Q3: How many hours should I study daily? Consistency is key. 3-4 hours of focused, quality study is far better than 10 hours of passive reading.
