Hello Aspirant,

If National Testing Agency rejects your application/admit card due to any discrepancy, they inform you through mail and SMS before rejection so that you can correct it under the given time period.

You need not to take any tension of that because without informing you they cannot reject your application due to some reason.

I hope this information helps you.

Good Luck!!
