Hello student,

In simple words, YES you are eligible for NDA for army wing only. See, there is no such issue you can easily join NDA but you will be restricted till Army wing

As you do not studied mathematics in your class 12th that will not allow you for Navy and air force due to this you will be preffered for NDA only in army wing.

You need to pass mathematics examination separately if your goal is navy and air force wing. You can take coaching for it as well.
