AP exam books(chem, apush, and english lang)

hello,
in about 2.5 weeks i will be taking my AP exams. I am most worried about Chem. in complete honesty i hadn’t learned very much in that class. I was wondering if any of you were stuck in the same boat? What book would you recommend i get for these 3 classes? consider my time predicament and my lack of concrete chem knowledge. and and i’m striving for a 5 in these classes(even chem).please note the short period of time i have left. if u have any helpful l information or personal experience-story, drop a comment…don’t be shy!
