Hi aspirant,

No you would not be eligible for NDA/NA examination in 2022 or further. According to the current eligibility criteria set up by the UPSC, the body which conducts the NDA examination a candidate needs to be aged between 16.5 to 19.5 years in order to be eligible for the examination. Following that the last attempt that you could have appeared has already passed with the completion of NDA 2 2021.

Hope it helps!!
