here are the answers to your exam
1) steric hindrance at the circled carbon determines the chemoselectivity
2) when you open an epoxide under lewis acid conditions, the regioselectivity is determined by the carbon that can best stabilize a positive charge, not the carbon that is the least sterically hindered
3)
a) TsCl, pyridine
b) DBU
giving you the alkene, followed by mCPBA
4) False, the pKa of acetic acid is too low.

I took two terms of organic chem and they are the only courses in my history of going to school where I went into the final exams failing 
Needless to say, I dropped biochem as my major.

I used to work with a shitload of N-butyls, normal propyls, Isobutyls and Methyl Ehtels. Do I get any points. Mostly alchohols, acetates and ketones. mostly dealt with drying times and pigments.

bah I'm morally opposed to ACS standardized exams for ochem... they ask more about memorization than understanding of mechanisms and concepts. you're more likely to be penalized for not knowing the name of the reaction than the arrow-pushing.

being that im in Law School and all, I don't know if I will ever make it out to an ACS conference. =).
My intro to O-Chem class was all about theory, then Ochem 2 and 3 were pretty much all reaction memorization. Granted, its easier to memorize a reaction if you know how to push electrons. Also, the tests gave us a beginning product and an end product and we had to use all the reactions we memorized to piece together the reaction process.
