Hello aspirant,

The NDA exam eligibility requirements stipulates that a candidate must be between the ages of 16.5 and 19.5.

A candidate for the NDA's army wing must have passed the 12th grade with the 10+2 school education pattern or an equivalent test administered by a university or state education board .

SInce you have crossed this age limit, you are not eligible for NDA.

thank you

hope this information helps you.
