Any advices for a rising junior?

I know the intensity and average workloads of AP classes differ from school to school. As a sophomore at a huge public school(LBSS) I’m pondering over increasing my AP workloads by taking AP chem. In my sophomore year, I’m taking only one AP class- AP CS Principles. My junior year schedule will be tentatively as follows.

AP Language
AP Physics 1
AP CS A
HN US History
HN Pre-Calc
World Language 3
PE

I’m considering taking PE over summer and adding AP Chem to the above schedule. I’m afraid if this would take too much of my time and energy and eventually play against my benefits. I’m on a varsity team and have to take the SAT/ACT and possibly two other SAT subject tests aside from AP tests all in my junior year. I’m aiming at UVA (engineering school if possible) and want to make my case strong enough.

By graduation, I might end up with 7 AP classes. with the rest of other classes at the honors level. At a huge VA public high school like LBSS, how many APs (on average) are required and what AP classes are recommended to get into UVA?

PS. I’m an Asian boy.

I feel like UVA is going to compare your course rigor/schedule with the students of your high school, as a large high school like yours could have tens of AP courses offered, or only a few. If I recall, on one of the admission blogs it is said that UVA really investigates your GPA and courses to see how you have performed at your high school when compared to your peers. I can tell you that by the time I finished high school, I had taken 13 AP’s (out of 15 or so offered) and my course rigor was essentially the most difficult that I could have taken. But I would ask Dean J for guidance; this is just a jog of my memory.
