see Ben, i knew these sophomores would figure it out eventually. or maybe Parker's just awesome like that, and nobody else is, lol.
--one of the best places that i can remember that was helpful for reviews was Sparknotes, you can make an account and get on and take practice tests which are pretty good. review guides like REA or Princeton review also give you a lot of practice tests which are good too. and you can usually get those off of Amazon or eBay

has summaries of the textbook, at least if you guys are using the same one as we did last year which i'm assuming you are. it's helpful if you wanna review a specific section or time period but you don't wanna reread the whole flippin' chapter over again.

these 3 websites are all outline sort of things, some of them are good and others aren't so much. but they're kinda helpful if you're studying for writing essays and you want general sort of topics and ideas to go off of.

i think these are all the websites i have, but if i dig anymore up i'll letcha guys know. good luck with reviews and on the test!!!
