Dear Aspirant,

It seems that you are asking for B.A in defence and strategic studies.

So the eligibility for this course is 10+2 pass with 50% in any stream from recognised education board

So the as per the eligibility maths is not the mandatory subject. Even you have not studied maths then also you are eligible for this course

Hope this helps

According to NDA required educational qualification, the minimum eligibilty is as follows:

1. For Army Wing of NDA- Passed class 12 or equivalent examination from a recognized board
2. For Air Force and Navel Wing s of NDA and 10+2 Cadet Entry Scheme at INA-Passed Class 12 or equivalent examination with Physics and Mathematics

Since, you did not have mathematics in your +2 level, you can join the Army Wing of NDA only. I hope this helps you!
