What is the Exam?
The National Defence Academy (NDA) examination is the premier gateway for youth to join the Indian Armed Forces—Army, Navy, and Air Force—as commissioned officers. Conducted twice annually by the Union Public Service Commission (UPSC), the exam serves as a highly prestigious national-level test that selects candidates based on a rigorous written examination followed by the Service Selection Board (SSB) interview. We at Exam Bhai view the NDA not just as a career choice, but as a commitment to national service, requiring both intellectual sharpness and physical endurance.

Focus on NCERT books for basics and dedicate at least 2 hours daily to newspaper reading for Current Affairs. Start your subject-wise practice for Defence exams early to identify weak areas.
