EC’s look great. Varied, from sports to personal passion to volunteerism, with founding or leadership positions in most. I would particularly emphasis the personal passion project (crosswords).
Some other thoughts, if you’re chasing highly rejective schools.
Have you also taken a practice test for the ACT and determined you do better/prefer the SAT? Many end up doing better on one or the other, and both are accepted and equally valued at any college, so you should find which one best represents you. All of my kids started out assuming SAT and two ended up using their ACT scores.
How were your AP scores Sophomore year?
I’m guessing by this you mean your school grants 4.33 for A+ grades? I would try recalculating your GPA on your own assuming and A or A+ are both 4.0 and then you will have a sense of how you compare to the typical UW GPA.
At your HS the highest math available to a Junior is not one of the AP Calc course (and doesn’t sound like you took Calc previously)? Does that come senior year?
To be clear, I’m not suggesting this is a problem in any way – it is not. Just curious based on the way it is described.
Good luck! Just keep doing what you’re doing and enjoy it.
