is the mcgraw-hill PCAT book any useful? and what's a good book for studying the verbal and reading section and calculus? I still have my high school notes and first year calculus notes, is there any other book I should get? I also have my textbook here: http://www.049501169x.com/, is this any good? it's got integration, differentiation by parts, la hiptal's rule, a bit of logarithms functions, limits, derivatives, integrals, first-order differential equations, so i need to know series and anything else like that?
