Hello,

Eligibility criteria for India Navy or Airforce is candidates must have secured 60% minimum aggregate in 12 having physics and mathematics as major subjects and  chemistry/biology and computer science as optional subjects.

So check for your eligibility, if your intermediate percentage is above 60% and had physics and maths as compulsory subjects then you can apply for Indian Navy or Airforce and go through the selection rounds.

Check out what is the procedure and prepare yourself accordingly. Major tests are written, medical and interview round. So practice for them.

Hope it helps!
