All American colleges compare your scores to your own school and the classes your own school offers. As long as you remain top of your class throughout high school, you can make it into an Ivy League college. If you really want to take an AP class, you can self learn and register for the exam from the collegeboard website. Some AP classes can be easily self-learned. I have taken a few AP classes myself, so if you have questions, feel free to ask :)
