Congratulations on a very impressive academic record and high test scores!
Since you’ve apparently run out of AP classes at your school, look into taking some college classes in 12th grade. Most colleges will let a high school senior take one class a semester there - this can be exploited by taking one class a semester at more than one college. Make sure to check out the quality of the professor on Rate My Professor, if possible, and choose courses with good profs. You might be able to get a great letter from a college prof from a fall semester class, if you do outstanding work and participate enthusiastically, and go to office hours.
You took Calc BC in 10th grade and got a 5. That’s wonderful! But in 11th, you did AP Stat, instead of continuing on the advanced math track. If at all possible, take the next year of college math at a college nearby in 12th grade. If you have nothing better to do this summer, I’d suggest taking it this summer at a nearby college, if it’s possible, and then the subsequent year of college math in 12th grade at a nearby college. You’re competing against others who have done two years beyond Calc BC. If you can also continue comp sci at a nearby college this summer and next year, it would help, too.
Your academic qualifications are superb. Top grades, top SATs, likely national merit.
Can your family afford in-state tuition at a UC school? Frankly, this is your best bet, and will probably end up being where you’ll get admitted, since California admissions are race-blind, although they’re also test-blind - but you get to list National Merit as an award, and have a great GPA, so they’ll know you’re not just the best in an awful school with low academic standards (not that your school is one of those).
If your school has any great teachers for AP classes which can be taken without having prerequisite background, you should take them, just for life enrichment. Other AP history classes, AP Econ, AP art history, AP Psych, anything - IF they have great teachers. Register for 8 periods of classes, then drop two, and keep the best. That’s how to get the most out of your high school education. I guarantee you that if the teacher is fantastic, you’ll enjoy whatever the class is.
I’d only do the tutoring class if you want to, and cannot find something that you would rather do during that time. It’s not going to get you over the hurdle into an Ivy. It’s community service, but doesn’t show leadership or initiative. Now, if you founded a summer tutoring program to help the disadvantaged kids in your area catch up from the lost year of the pandemic, and recruited a lot of other bright young stars like you in all fields to join you in this, and helped a whole bunch of kids catch up this summer, that would show initiative, drive, leadership. THAT would be an Ivy-worthy community service project. You might be able to piggy-back onto a local Boys and Girls summer daycamp childcare program, to give each kid some academic catch up tutoring every day this summer. I’m not saying you have to do this. But you have the grades, you have the test scores, you have some awards. You need a community service project that does more than check the box - you need one that is head and shoulders above the rest, that makes you stand out. You want them to think you’re the guy who’s gonna found the next Khan Academy type of thing, not just get a degree in comp sci and get a job.
You’re going to need amazing essays, essays that show (not tell) something special about yourself, that make them think, “We need this guy here.”
If you make national merit, you might qualify for a full tuition scholarship, or even a full ride, at a southern or lesser mid western public college. The fact is, if you come out with comp sci, or math, or better yet, both, from any college, you will be in tremendous demand on the job market, even if it’s from a lesser college or university, and certainly from a UC. So you don’t have to do any of the things I’ve mentioned above. But I think that if you want to get into an Ivy or its equivalent, you need to add ‘over the top’ community service, preferably one that utilizes your comp sci and math skills, you need to show tremendous rigor in your 12th grade classes, so that means 6 AP or college classes, including further math, and comp sci too if you can get it, and you need to have outstanding essays.
You might actually be the sort of person who would benefit from a ‘for pay’ college admissions coach. You already have the toughest pieces of the puzzle - the grades and the scores. But you need guidance on the community service, planning for getting the rigorous classes you could get, in your area, and guidance on the essays, and application strategy. You can get a ton of good (and some bad) advice from here, but you might find it easier if you were guided by a good admissions advisor.
