Hello,

I hope you are doing fine, The date of birth mentioned in the application must be the same as that entered in the Matriculation or Secondary School Leaving Certificate. In short, candidates should be between the age of 16.5 years and 19.5 years to be eligible for the exam.

So yeah your are eligible for NDA Exam

I hope you find this information helpful. I wish you all the best for your future.

Good Luck
