I decided to self study AP environmental science, which I eventually received a 5 for. This was a textbook I was considering to use, but I found it to be difficult to read (not to mention a bit politically-oriented). I would recommend Raven and Berg for APES, which is more concise and comprehensive for the test. 
 
I'm a student and am taking a class using this book. I've found it very difficult to follow and short on explanations. Without additional resources, I would not be able to learn the material in this book.
