You never know how you did.  My friend think he fails and he got 97.  Since your test is compare with other taker.  The harder you feel, the more liekly other people are struggling too. On the other hand, if you feel easy, others are too.

I guess you have a good chance passsing. Goodluck.

Two things:

1. If it was as hard as you say, it will probably be curved pretty heavily.

2. If your result ends up being negative, and I truly hope it is not the case, don't let it define you as a person. We all understand the need to raise the bar in the professional arts but there is no logical reason to make it so hard for hard working people who simply want to get ahead to do it, except to generate retake fees for Prometric.
