The NDA/NA exam is conducted twice a year by the UPSC, and clearing it is the first step toward joining the Indian Armed Forces as an officer.

Step-by-Step NDA/NA 2025 Preparation Strategy

And this is where GKP’s books shine. Let’s explore this in detail later.
Step 5: Attempt Regular Mock Tests
Practice full-length mock tests every week. Analyze your performance:
- Where did you go wrong?
- How much time did each section take?
- Was there a pattern in the mistakes?
Improvement starts when you study your own mistakes.
Step 6: Stay Updated with Current Affairs
Read newspapers like The Hindu, Indian Express, or monthly magazines like Pratiyogita Darpan. Focus on:
- Defence news
- National & international events
- Government schemes
- Environmental issues
Step 7: Stay Physically and Mentally Fit
