Are you auto admit at Austin? In your major.
I’d assume you’ll get into all except maybe UCLA.
I would add Pitt because it’s a wonderful health school and they have they have wonderful diversity scholarships. It’s also colder than any school on your list, however.
You might take the ACT once more to improve the math score - focus in that area.
But you’ll be fine.
Congrats and good luck.
PS - don’t feature the Honor Societies as ECs - most assume they are fluff. But you have some good ones down there.
