Hi
ravikiran11235,
If you cancel today, the cancellation fee will be $200. You'll get a refund of $50. But if you're to book it again, it'll cost you $250 all over again. So your total expense would be
$250-$50+$250 = $450If you were to reschedule it for a later date today, that will cost you $150. The total you'll have spent is
$250+$150 = $400Agree with
warrior1991 that rescheduling seems to be a cheaper option, but not by much. It's okay to be nervous, especially if it's your first attempt. My personal advice would be to reschedule and gather yourself at peace and give it some space. You'll end up being a lot less tensed in the exam, and that'll improve your performance.
All the best!
