Refresher v Official Exams

[zeedonk]

As most of you know, the IAABO exam is on Monday. I am plowing my way through the rule book, case book and various prior exams in preparation. Feeling pretty confident, but trying to avoid overconfidence...

Question is- I am reviewing some refresher exams as well as "official" exams. We discussed very briefly in class that the refresher exams are made up of questions rejected for the "official" exam. Is this true, and if so, what am I to make of the difficulty I am having with a very recent (2008) refresher exam? Most of the other exams I'm practicing on have not given me too much trouble.

Test jitters?
