Hello Joshi,

yes you can apply for the exam, but you need to submit your 10+2 certificates in the document verification, and you need to born between july 2 2001 to july 4  2004. so it is better for you to write the exam after 12th.

Dear student!

In order to get into NDA, you need to clear the NDA entrance examination. Yes, even a 12th class student can give the examination. You can check the eligibility criteria for the exam and more details in he link provided below -
