Hi Chandan,

The NDA exam is held annually for admissions to training programs for the Navy, the Army and the Air Force. For eligibility to join the NDA, a candidate must be more than 16 years and 6 months old and less that  19 years and 6 months old. The DoB printed on your class 10 or class 12 marksheet will be considered which you can submit to the center after the results of NDA exam. As I can see, you are eligible to join the NDA.
