Preparing for the NDA (National Defence Academy) Written Exam is a journey filled with dedication, smart planning, and consistent effort. As the exam approaches, revision becomes the most critical phase of your preparation. Whether it's GAT (General Ability Test) or Mathematics, adopting effective and smart revision strategies can significantly boost your performance. In this blog, we will explore comprehensive revision techniques that will help you confidently approach the NDA written exam and maximize your chances of success.


Importance of Revision for NDA Written Exam

Revision isn't just about re-reading notes or flipping through pages. It's an active process that reinforces your understanding, enhances memory retention, and helps identify weak areas. In the final weeks before the NDA exam, smart revision can bridge the gap between average and outstanding scores.

NDA Written Exam Structure:
