I am self-studying both of these AP tests. Zero background in either subject (though I know some ecological stuff from biology that could be useful for environmental science). I've read the stickies on AP book suggestions, but I'm just looking for a little extra input before I make my final decisions.
So far I am thinking REA for Human Geography and PR + Smartypants for Environmental Sciences? Are these books enough to get a 4/5 on the AP exams (preferably 5)? Any other useful books? People here have said Smartypants is pretty good for ES but on amazon the reviews are pretty bad.
