Hello,

If you want to join INA then you take science stream. I'll describe you the joining process.

1. Candidate must have physics and mathematics in 12th. And candidate give the NDA examination.

2. Candidate nationality must be Indian and candidate should be male.

So this is the basic criteria. You choose science in your 11th class otherwise you can eligible for NDA examination.  Prepare yourself as  INA officer dear.

All the best.
