I am interested to know how IV rates as well. I seem to have done pretty damn well on it but I don't want to have false confidence if it actually a diluted version of what August 16 will offer.
i thought aamc IV matched up pretty well in difficulty of the real test, at least better than the earlier aamc tests anyway...
AAMC IV: 10V 12P 12B
April 2003: 12V 14P 10B
i f'ed up a whole passage in biology on the actual test (the proctor called 5 minutes and I panicked), so that score was kind of off, but otherwise i thought aamc IV, V and VI were pretty good indicators.
good luck august mcat'ers! here's hoping everyone gets the form they deserve 🙂
