Unfortunately, not all college's/professors are happy with the the AP classes taken in high school, or will allow you to use them for college credit. I can't say for sure the way things are now (I graduated from high school in '94 -things may be completely different-), but my sister and I both took AP level courses for several classes in high school; we both had just about perfect grades, and neither of us were allowed to carry every AP class over for college credit.
I did take AP calculus in high school and calc I in college; I found the material and the expectations -in college- to be much more than it was in high school. It was more rigorous, things moved at a quicker pace & they went through the material more in depth. Honestly, at first I was ticked off that I had to re take it, but in a way it was like taking a whole new class. I got a lot more out of it, and a better of understanding of concepts that I didn't even realize I needed a better understanding off.
I was actually just talking to my sister about this a few weeks ago, and both of us felt that we learned more and got more out of the classes that we re-took in college. I can honestly say if I had gone directly to the next level with everything when I got to college I think it would have put me at a disadvantage, and I'm glad I wasn't able to carry all those classes over.
One thing I've noticed that was going on when I was in high school, but seems to be getting more intense as the years go by is this need, and this push students are given to "speed" through everything as fast as possible. They are really pushing students (if their grades indicate they should take AP classes) to get college classes out of the way in high school, and pushing too hard in general. One of my employee's has a daughter in 12th grade, she takes AP classes, and does extrmemely well in them, but she has about 6 hours of homework and studying a night! I think this philosophy tends to leave teeneagers unprepared, and many get burnt out quickly. Don't push yourself too hard to get everything done fast. It's better to take a couple classes again than to go into new classes and fall behind because the AP class didn't cover enough material. Highschool classes, AP or not are not like a college course (at least in my experience).
If you really are set on getting ahead you could take the courses over the summer at the college your attending if it's in your hometown, and if it's not you could take them at a local university. My advice though would be to take at least some of the classes again (if you have a full AP load) in college and look at AP as college prep, a foundation so to speak. I haven't been in high school, or college for a while so if I'm way off I apologize, but I think it probably hasn't changed that much.
Regardless of what you do, good luck!
