I haven't taken the MCAT yet, but I've noticed something about the way I take the verbal sections on practice tests and changing it has helped me improve my scores. Originally, when I started taking practice tests, I was trying to read the passages really quickly so I could get done in time. I was so focused on going fast that I wasn't comprehending the passages well at all. By relaxing myself and making sure I was understanding as I read (even if it took me a little longer to read), I was able to get done more quickly and improve my scores because I wouldn't have to go back to the passage multiple times. I don't know that this is an issue for you, but it helped me. Good luck!
