Okay, i took 2 topscorers exams, and I keep getting 18,18,17 for the science, does that mean im in trouble???

no man.
just do your best.
learn from it

No you will prob score a little higher on the actual DAT. Depending on what you are shooting for you should be good.

Yeah yesterday I took topscore 2 and got

bio 16
chem 21
ochem 17

i was very happy with the chem but disappointed with the other two. the bio had about 5 questions on classification which i did not think was fair, and i also just made some stupid mistakes. I think my biggest problem now is that I know most of the stuff but I make stupid errors.
