What is the most effective way to prepare for NDA exam (Army Wing Only) for a student who has dropped Maths after passing out Class X.

Jaguar replied | 22 Feb

If Your preferred choice is army then Maths not that much matters. All you have to do is to qualify but you have to do good in all other parts of the exam.
