Hi aspirant,

You want to tell that you are 18.8 years old don't you. According to the current age limit set up by UPSC the body which conducts the NDA examination, a candidate needs to age between 16.5 to 19.5 years to be eligible for writing the examination. So following that you can definitely appear for NDA 1 2022 as you will be within the the upper age limit however you cannot appear for NDA 2 examination as the maximum age limit would be crossed.

Hope it helps;!
