The NDA exam tests a candidate's knowledge in mathematics, general ability, and overall personality. It also includes physical fitness tests and the SSB interview. Starting preparation early, particularly in 11th and 12th, gives students ample time to understand the concepts, practice rigorously, and improve their skills progressively.
