I think you have a much higher than average chance at any school, but I would still say like 35ish percent for Stanford and MIT and the ivies. I have similar stats with a 1570 and an 800 on Math 2 and Chem and I got rejected from Stanford REA. If you want help deciding what school to apply EA and a more accurate chance, I would recommend looking at some of the threads from this year to see what students got accepted to schools with their stats. http://talk.collegeconfidential.com/stanford-university/2113339-stanford-class-of-2023-rea-results-thread-p1.html
Here’s the Stanford thread for this year. There’s a wide variety of SAT scores that got accepted, so there are a lot of people with high SATs who didn’t get in. Maybe look at some similar threads for MIT and the ivies to get a better view of what schools you have a higher chance at and where to apply early.
