pKa, pKb, pH relationships - know them like the back of your hand. Single most recurring topic, easily. There are concept questions, but the overwhelming majority of the test is problems, so have your formulas memorized. If you come across a problem that's going to take a long time to work out, skip it, make a note, and come back to it - all the problems count the same; working out a multiple equilibrium problem is going to count the same as knowing what a coversion dynode in a PMT does (example, wasn't actually on there). I don't know how your teacher will grade, but it's my understanding there's a fairly hefty curve on it, with the national average of however many right set at a C, or C+.
GL, feel free to ask anything more specific, but won't give specific questions away or anything.
