There is a pdf (in case formatting changes) and a word document (so you can edit it to your liking). For the most part, it follows the recommended sequence from College Board, but I did move a few things around to my liking. EX: Instead of waiting until the end of the year, I chose to put eutrophication in unit 1 with the biogeochemical cycles and HIPPCO in unit 2 with biodiversity.
I give my AP Environmental Science students this packet to review in the evenings starting two weeks before their AP exam. They cover one section at a time and I quiz them over the material the next day in class. Please see the thumbnail pictures. The review is not interactive and there are not a lot of pictures! It covers the definitions and main points from throughout the year. My students highlight what they remember and could explain to me. If they don't remember something at all and need more information than the brief reminder in the packet, they have to look back at their class notes, reading notes, or do some research (sadly, the review can't cover everything in too much detail or it would be forever long). It works really well for my students and myself; if you decide you want to buy it, I hope you have just as much luck with it!
