When I took it you got a score on the back it had percentile break down, from what i remember it said only 2.6% of the people who took the same exam I did failed, whatever that means. Pretty sure they use the same grading system for passing.
Is it super easy to pass because of the curving? I have some friends who just did it and found it really hard. They are really worried. They haven't gotten back their scores yet though.
