There’s no reason to accelerate like this. You already are ahead, and you will have room in your schedule for AP Calculus. Algebra II provides an extremely important foundation for Calculus, and by accelerating over the summer, you may be at a disadvantage compared to other students.
There is NO reason to accelerate your math courses just to take AP Stats. AP Stats is an “AP Light” and there’s no reason for it, especially if you aren’t interested in math in the future. If you want to take statistics, take it in college, but there is no reason to try to jump ahead just to take it in high school.
