Hi everyone,
I took the Pre-FPGEE yesterday. It was a bit of a relief to me, because I got 121, but I don't think this is representative about my preparedness for the real exam- the questiones were on several chapters only, not the whole blueprint! Also, you can't check the right answers, they just tell you the score. Anyway, I advise you to take it, even though it's expensive!

Good luck!
