| Preparation time before first attempt | About two years | 2 months to 1 year |
| Board exams | Covered inside the programme | Already done |
| SSB & personality | Built gradually over two years | Focused SSB training before the interview |
| Physical fitness | Two years of daily PT | Daily PT during the course |
| Best for | Students sure about a defence career early | Students with strong Maths, or who decide later |
Why starting after Class 10 helps
- Your first NDA attempt is strong. UPSC lets Class 12 students apply, so a Foundation student can make a well-prepared attempt while still at school.
- School and NDA syllabus overlap. Algebra, trigonometry, calculus, vectors and probability are in both, so you study them once, properly.
- Time to grow the SSB qualities. Confidence, communication and leadership take time. Two years of group tasks, discussions and talks make a visible difference.
- Fitness without a rush. Daily PT over two years gets you ready for the SSB and the medical.
- The right stream. Choosing PCM in Class 11 keeps the Army, Air Force and Navy wings open.
NDDA also runs a three-year Foundation programme after Class 9 and a one-year programme after Class 11; see the Foundation course page for the details and fees.
When starting after Class 12 makes sense
- You already have strong Class 12 Maths and need exam-focused practice.
- You decided on a defence career late in Class 12 or after the boards.
- You attempted NDA once and want a structured second attempt.
- You want a lower total cost: the 1-year NDA course is ₹70,000 without hostel, or ₹1,54,000 with hostel.

Our advice
If you are in Class 10 and sure you want to wear the uniform, start now with the Foundation programme and take PCM. If you are already in or past Class 12, don't wait for "the perfect time": the next exam is NDA (I) 2027 on 11 April 2027, and a 6-month or 1-year course started now prepares you for it. Talk to our counsellor to match the course to your age and exam date.

FAQs
Is it better to start NDA preparation after 10th or after 12th?
Starting after Class 10 gives two full years to build Maths, GAT and fitness before the first attempt, which is usually made while in Class 12. Starting after Class 12 works well for students who already have strong Maths and want focused coaching for the next exam. The right choice depends on your base and how many attempts you have left.
Can I write the NDA exam while studying in Class 12?
Yes. UPSC allows candidates who are appearing in the Class 12 exam under the 10+2 pattern to apply for the NDA exam, subject to the age limits in the notification.
Which stream should I take after Class 10 for NDA?
Take Physics, Chemistry and Mathematics (PCM) in Class 11–12 if you want to keep every option open. The Army wing accepts Class 12 in any stream, but the Air Force and Navy wings and the Naval Academy need Class 12 with PCM.
Will NDA Foundation coaching affect my board exams?
NDDA's Foundation programme combines schooling with NDA preparation, so the Class 11–12 syllabus and board exams are covered alongside NDA Maths, GAT, SSB and PT. Many NDA Maths topics are also part of the Class 11–12 syllabus.
What are the age limits for NDA?
Candidates must be unmarried and roughly 16½ to 19½ years old at the start of the course. For NDA-II 2026, candidates had to be born between 1 January 2008 and 1 January 2011. Check the exact dates in each UPSC notification.
