Guys (and girls), calm down! 25 full length practice tests is way too much. I took like 4 and even that was a bit excessive. I think you need to get the pace down and everything because the test will last almost 10 hours with breaks and evrything, but these are still examples of the question types you might encounter on the MCAT. The truth is that the real MCAT looks very little like the Kaplan/PR tests (except for the verbal section). The real deal is very passage based and can't be studied for. I'm not a genius by any stretch of the imagination, but after a thorough review of the materials and SOME practice tests, I called it quits and played some Crash Bandicoot and did much better than I thought I would. Also, if you have to take extra full length practice tests, do the AAMC ones, they're the only ones that are fairly accurate to the real deal. Good luck.
