Dont' sweat it. It is a practice MCAT, meaning just that. Sure it is a very good representation of the actual test, but it isnt an indication of how you will do. There are multiple versions of the MCAT, and sometimes a group of students get one that is harder than the rest. That is just the way that it works out. I didnt do very well on my practice one either.
Actually I didnt do that well on my actual MCAT....I got a 21 (5V, 8PS, 8BS, N). I am attending UHS this fall.
That just goes to show you that the MCAT isnt everything, but if you have a good score, along with experiences and grades, you will have an easier time than I did.
Good luck
