Dear aspirant

The age limit for giving NDA exam is between 16.5-19.5 years. NDA happens twice in year. So you will be eligible only when you will be appearing for 12th exam. So by that time you will be 17.5years almost so if we calculate then you may have only 3-4 attempts to clear the NDA exam.

The age limit for NDA 2022 is given below

You will be eligible for NDA 2023 only so you can calculate number of attempt according to this.

You can refer the link below for more details about eligibility
