Aleksander,
Blame your facility, not GARP. The testing facility where I sat for the exam was frigid!
When you say "I felt the exam was not that difficult", what do you mean? It was not that difficult in relation to what? The actual exam questions were considerably more difficult than the questions I used for practice.
FYI, I have sat for actuarial exams, which are notoriously difficult, and I would say that the 2012 May Part 1 exam was as difficult as any of the actuary exams.
in general, many questions were considerably more difficult than the prior year's exams (e.g. FRM Handbook questions from past exams, old GARP exams, etc.)
I would say it was on par with David's mock exam for difficulty - a lot of scenarios which were slightly out of the norm, and styles of questions that I hadn't seen before. It started off with a few more challenging questions in the first 10, and that had me a little bit flustered (on difficulty and time), so then felt i had to overcompensate by rushing through some of the more straight-forward questions (hopefully without botching the calcs). Correct me if i am wrong, but did the 1st question on binomial pricing even provide the strike price?? (assumed ATM).
