Hello,

The NDA/NA Examination is conducted by UPSC, Union Public Service Commission.

Now Regarding you query of difference in Date Of Birth mentioned in Class X Marksheet and your Aadhar Card, so I would like to tell you that these differences in your DOB will definitely cause problem as your addhar card would be used to verify your information.

Also the DOB you have to enter while filling the form is the one that is mentioned in your matriculation certificate.

So, you can fill the form and allso get the DOB corrected in your Aadhar Card, so by the time of examination you will have correct DOB in your Aadhar card.
