if am born in 09/08/2005 and now I am studying in 10 class and I want to give Nda exam so muje exam 12 ke baad Deni hai to mere pass Kitne attempts hai my age is now 15
There is no such restrictions about the attempts. You can give number of times the NDA exam before the age of 19 . So after completion of 12th standard you have 2 attempt. One is at the age of 18 that is when you give 12th exam and one is at the age of 19.
Hope my answer will help you
