lol, I magically went up 6 points from AAMC V (controlled, timed, full-effort) one week before the MCAT to the actual MCAT. 2 point increase in each sub-section. On practice exams I was consistantly around 30. I thought I bombed the VR section. Dude, it was 2 easy, 2 moderate, and 5 HARD passages. The hardest passage had 10 questions with it too! I ended up bubbling about 5 in on that passage in the last minute. Maybe that was the experimental section...
Blah, in any case, don't drive yourself nuts worrying about it!
