FE exam tomorrow

i did some reviewing. all the stuff dealing w/ my major i had trouble with and had to look up the equations. when i got to the chemistry section, i got 90% of them w/o even having to look up an equation. i even remember molecular weights of different elements. i swear all the questions dealing w/ my major seem harder for me since i'm used to problems that take a half hr vs 2 minutes and so i dont have the simple equations memorized as much.
