Balancing Class 12 board exams with NDA preparation requires a disciplined, time-blocked schedule focusing on Mathematics and General Ability Test (GAT). We at Exam Bhai recommend dedicating 3 hours daily to NDA topics, integrating NCERT concepts, and utilizing consistent mock testing to master time management and conceptual clarity for success.

- Mathematics Focus: The Mathematics paper for NDA is at the level of class 11 and 12. Focus on solving problems quickly. Use Exam Bhai’s specialized NDA test series to practice speed and accuracy.
- Current Affairs: Spend 30 minutes daily on news apps or editorial analysis to stay updated on national and international events.
