No one can chance a 10th grader but you’re in AP bio as a 10th grader, so you are way ahead.
One should worry about learning, not grades but most U Wash students are not straight A and outside of CS, it’s competitive but not impossible to get in.
No need to take the AP pre calc test. As it is, you’ll be in Calc next year so you are way ahead.
Pick two ECs and do well and grow in them. You’ve got 6 or 8. You need quality, not quantity.
Sounds to me like you are well on your way to college admission success. Don’t worry about others - you do you. But be a kid - it sounds like you aren’t.
Come back in a year and update us and then you can do a chance me.
But it’s too early to chance - but you’re on a good path.
Ps - UW won’t look at your SAT. They only look at a small percentage of marginal apps. That doesn’t sound like you.
