Hello Candidate,

The eligibility criteria for the NDA Exam is listed below.

• You must be either in 12th or have passed the 12th class
• Your age must lie between 16.5 - 19.5 years
• You must be an Indian citizen

Now as in the december 2022, you will be above 16.5 years and also you will be in 12th, so surely you can give the NDA 1 Exam of 2022. But you are not eligible for NDA 2022 April, as your age will be less than 16.5 then. Also you can give further NDA Exams till your age goes above 19.5 years. For more, visit the link given below.
