The best is what you'll realize in roughly 3-4 years: HS grades mean absolute sh*t.
It looks like your prof is teaching you basic organic chem. That really shouldn't be all that hard. Count carbons, learn the general form for organic molecules. Now if she's asking you to do dehydrohalogenation on Methyl, Primary, Secondary, and Tertiary alcohols, you can start bitching. Sn1...Sn2...E1...E2...fun stuff. All memorizaiton.
