What does it take to get a decent score (>/= 30) on the MCAT?

I think the scoring must have changed from the 1980's...

Anyway, what I did was PRACTICE PRACTICE PRACTICE tests.  I got a couple of MCAT study books and went over everything.  I got a high score (high enough to qualify me for MENSA), got accepted at several med schools and am now a practicing physician.

I also remember memorizing stupid things, like the square root of two, because we were not allowed to use calculators on the math portion.  I don't know if that has changed or not.

I suggest not taking the exam until you feel you are prepared, and you'll know you are prepared when you can breeze through a practice test.

Good luck.
