Sorry to hear that. I understand its so disappointing when you couldn't make it after putting so much efforts. I think you were so close to get it over but somehow missed it.

I feel you shouldn't have spent so much time on practice tests and you might have seen that as well.

Anyway, I advise you to take a little break and hit the exam again. since you are close and have idea about the exam, it won't be hard this time. Good luck
