Hello,
Different colleges have different admission procedures. But, you need to score a minimum of 60% to become eligible.

Hello,
You can change your NDA Examination Center, but if I say it genuinely it is a very strenuous task. First of all you need to contact UPSC [But keep it in mind that you need to have very prominent/solid reason for that why you want to change your examination center. You need to have a very convincing behavior when you are approaching them, because chances are rare.
Hoping that you will get your desired center.

You can check the link predictor for better results
