I need some help. I'm studying for the pcat june 2007 and have been having alot of trouble finishing the pcat practice exams sections on chemistry. There are those questions which require no thought at all, and those big stoichiometry problems that eat up too much of my time. I've done all the preparation necessary to take the chemistry section. I've studied. I wouldn't say I had great profs in undergrad but I did okay. I even feel they might have been too easy now. For 48 questions in 30 minutes, I see a wide range of easy and hard questions mixed in. What I am aiming for on the real one is at least to complete 80% of the chem section. If any dr. phils can give it to me straight, i would appreciate it.
