I agree that these are questions for your teachers an guidance staff.
Pre-Calc and AP Stats are typically full year courses, so it’s a very aggressive plan. Having said that, very talented math students can probably get through it without issues. My D was taking online Number Theory and Combinatorics classes along with weekly math club meetings/homework and competitions at the same time as Pre-Calc. But there were probably 5-10 students in her 550 person class that I think would succeed at it.
