Age limit for this year (2020) was as follows- minimum age should be 15.7 years (DOB 1st January 2005, not later than that), or 16 years during the commencement of course. Maximum age should be 18.7 years (not earlier than 2nd January 2002)/ 19 years during the commencement of course.

If you fall into this criteria in the year you want to give the exam (ie are between 15.7 and 18.7 years then), you can give the exam in 2020. The criteria can also change with time, so keep up to date with the official websites.

Hey.

the age criteria is 16.5 years to 19.5 years for the eligibility of nda. calculating that, you are eligible for NDA 1 2022.

you are already 18 yrs old and will be 19 in 2021. so in 1st exam of 2022 you can appear. that will be your last attempt.

sometimes age criteria will be changed, so just wait for eligibility in the official notification too.

but you do have 1 chance in 2022
