Hey,

This is not true. The admission in NDA is done only through offline written test, SSB interview and medical test. Even if you score more than 90% , you will have to go through all the rounds and pass them.

The eligibility criteria is that the candidate must have passed 10+2 from any stream for army and 10+2 with Physics and mathematics as subjects for navy and airforce. Kindly check the link below to see more details:

Hope this helps!
