I'm taking both AP Biology and AP Earth and Environmental next semester. I have a few questions, so I figured I'd run through and ask a few questions about the courses before I start.

What is the most important part of each course that you spent the most time learning about? Where do the courses overlap?

What textbook(s) did you use for the course(s) and which textbooks do you think were the most helpful?

Biology is a fairly broad aspect that does incorporate some earth and environmental topics. I think they will coincide at some point. 

However, biology is more broad, so it also covers topics in chemistry, then starts going into macromolecules: proteins, DNA, enzymes.

Cool beans. I guess the course differs between schools because of the broad subjects they cover, too. Thanks, abb0t! You're my heroooooo. ;)
