It really depends on what type of student you are, and what the school will allow. In my district, really bright, way ahead of the curve students get virtually no opportunity to take classes that are geared to their level until high school. Once they get into high school, they can maneuver themselves into almost all AP classes and get a very good education while in high school. Essentially, they get an education equivalent to the first two years of college, while staying in a high school environment. They take AP sciences without ever having taken high school sciences. They accelerate their math, take BC Calc in 11th and multivariable calc in senior year. They take multiple AP histories. They take AP levels in anything they can, assuming that the teacher is good, to get a broad college level education in high school.
So, if you are the kind of very bright, highly motivated student who has been frustrated by the slow pace of middle school, I suggest that you plan for all AP classes. I assume that your school requires that you take honors English 9 and 10, then allows you to take AP Lang, followed by AP Lit. You take whichever math you’re up to, at the honors level, and after precalc you take Calc BC. If you are allowed to do it, you take any of the following sciences in 9th grade: AP Environmental, AP Chem, AP Bio. If you can do it, I would recommend AP Chem first, because the chem will come in handy for AP Bio, but AP Bio doesn’t help you with AP Chem (except in that you have to learn a little bit of Chem for AP Bio). I would wait on taking physics at all until after you have Calc BC, or at least simultaneously with Calc BC, so I’d recommend doing AP Chem in 9th, AP Bio in 10th, and Physics C (both semesters) in 11th. If you are the sort of student who will have Calc by senior year, you take only Physics C - you don’t take Physics 1 and 2, followed by Physics C 2 semesters. Then, if you want to take AP Environ in 12th, great. If you don’t want to take it, and are interested in medicine or dentistry, audit Organic Chem at the local college (you don’t want to make a college transcript, but if you’re really that amazing, go ahead and take it for credit in 12th grade, and make the college transcript record of it).
Combine these with as many AP levels as you like of everything else, as long as they have a good teacher, to obtain the broadest, best education that you can while in high school.
This recommendation is only for a very bright, very precocious, highly motivated student, and only for the sake of wringing every opportune drop out of your high school education. Mere mortal students should take three years of honors level sciences and then take an AP science. They should take a mix of classes at their level, which is commonly, for a good student, honors, with maybe one or two AP classes a year. They also do sports, music, theater, all sorts of other things, for a normal, well-rounded high school experience.
That’s why I say it depends on what type of student you are. Discuss it with your parents, and your high school advisor. Understand that you can always drop down from AP level to honors level, but usually you cannot jump up mid-semester to join an AP class - they move too fast.
