Dear Aslma, you can join the Indian Army at various levels. As of now as you are still in your 11th, we shall help you with how to join the Indian Army after 12th. You can also join the Army after your graduation. Usually Candidates can join Indian Army after their 12th if they have studied Physics, Chemistry and Mathematics in their 12th. But because you are a Commerce student, you may have to join as a soldier. But if you can complete your graduation and appear for NDA exam, you can join the army. Or the other way is to join NCC. If you are a NCC Cadet, then you can appear for SSB and join the Army.
