You don’t have to - and more importantly you shouldn’t - take AP for every single class. Only take what you can handle, and most students can’t handle 6 or 7 APs at the same time. Strong student can usually handle maybe 3 or so, but it definitely varies. You want to challenge yourself, not overwhelm yourself. Have you taken any AP classes yet? How did you feel about the workload? What other classes are you taking? It is fine to take a mix of regular classes and AP classes. And with that I agree with others that you speak with your guidance counselor as well the teachers of subjects you think you might want to take an AP in.
