Talk to your guidance counselor about all of this. You are panicking about APs…your GC can include the fact that you were not able to take APs because of your schedule in their recommendation. But find out if your school would even give you credit…and if so, do you really want to add another online class on top of your other presumably online classes (because of covid)? Focus your efforts on to your HS classes.
Also how good are you at self-paced? I am one of those people who will attend classes and do my homework and keep up with schedules…but I am terrible without a structure.
