is it POSSIBLE to do well in AP Physics? well sure it is possible, anything is possible.Now is it likely you will do well in AP physics without doing regular or honors physics? I would have to say no,it is not likely because of the fact that you are doing college work, just in a highschool setting, so if you take AP physics with out learning the basics, you will mostlikely struggle or have to study alot harder then the rest of the students just to "stay afloat" and understand what is being said, while all the other students are working hard to get a good grade. I would advise you talk to you teacher to get extra help, or ask if s/he would recomend you transfering to honors physics or regular physics.
