Unfortunately I had scheduled my test a month after I passed my audit and did not think logically enough about how much study time I really needed.

I knew walking in I was likely to fail (although I did try my hardest).

It wasn't that the questions were particularly "hard", it's just that I didn't know them...at all...As in, I couldn't even guess the answer of many of them.

I took 2.5 hours on the questions I knew and an additional hour on detailed review.
