hey, we had the same passages. I h8'ed lizzard passage, at least one question made no sense in that passage
My impression:
Overall: I h8 CRT screen so much. Nobody uses 800x600 resolution on 17" screens anymore. Every time I had to pull the periodic table, it would occupy the whole screen and I could not see the question anymore. That was annoying. Plus, I was getting tired of scrolling through passages. The test center was HOT, I was sweating through WS and BS. Also, who in the hell solves any problems on dry-erase board. Never used and will never use it again.
PS: did not like the earth-meteorite passage, had at least one question that I had to guess because i could not find the answer in the passage for whatever reason. Did not like the torque passage, my weakest link. Transition metal passage... hm, it took me forever to balance the equation which did not come out well. I am sure I could balance it, but it just did not work so I had to take a guess. Plus I had to write with huge letters on this dry erase board... never used it, that thing is so ******ed. What's wrong with paper and pen? I guess it is easy to sneak the notes out of the test center.
VR: ok, had hard passages.
WS: nah
BS. Poor chipmonks and dogs. Had quite a bit of Physeo. Had a few genetics questions, but not that many. I would've liked to see more molecular bio passages. I had a couple ambigious questions that could give a couple answers. Most of it was passage-based which was ok. It was definitely challelnging, but it could be worth. During last years MCAT we had a non-Mendelian genetics passage was was terrible.
Good luck to those taking it within the next month or two.
