Hi Sharayu,

You can join the Indian Navy through NDS and TED entries. For those pursuing 12th the cadets for NDS role should have passed 10+2 with physics and mathematics and should be under 19 years and they are selected based on written test.The exam is conducted twice a year.For TES there will be direct interview based on 12th cut off.For this you should have passed 10+2 with a aggregate of 70% with physics,chemistry and mathematics from a recognised education board.

Hope it helps.

All the best!!!
