Dear Aspirant,

Every step is open for you to join Indian Army as a officer or soldier, lets first talk about the ways you can choose-

1- After 12th

Here you have two options, first one is to join as a soldier by participating in rally bharti of your state and the second one is that you can participate in NDA entrance examination, there is not any compulsory subject to appear in NDA for Indian Army, you can just appear for the exam. One thing is that you need to clear the Mathematics part and its compulsory to pass, so focus on your maths, rest is you have already studied like English and General Ability Test.

2- After Graduation

You can complete your graduation with any field, and can give the CDS entrance examination, no matter what you have taken in 12th.

Best Of Luck!!!

Hello, for Air Force and Navy, students required  math and physics as subjects in class 12. But you are eligible for the Army because the eligibility criteria state that candidates must have passed or be enrolled in class 12 in any stream from a recognized board.

Candidates must be between the ages of 16.5 and 19.5 years old.

The syllabus of NDA consists of Mathematics, English, General Knowledge, history, geography, etc.

You have to prepare a lot for maths because you are not a maths students. First of all have a close look at the syllabus and then work on your weak topics. Prepare your short notes for revision. Also join some mock test series. Learn from the mistakes that you have committed in the mock test and try not to commit them again.

Hope this helps
