What are my chances for Ivies/Williams/Amherst College/Swarthmore/Bowdoin?

First time in May. SAT: 2250 770 Critical Reading, 770 writing, 710 math.
I had been scoring 800s or high 700s on my math sections and misread three questions on the day of the test; I am planning on retaking in the fall and have absolute faith that I can get my math score up.)

Straight As (4.0) throughout all of high school, except for two A-s freshman year.
All honors/advanced/AP classes in major subjects + Spanish (except physics this year bc advanced wasn’t offered)
Have taken all APs offered at my two schools. 5 on AP Global, took APUSH and AP Lit this year and believe I pulled 5s on both.

Will take SAT2s next month. Am planning on US and Literature; should I be taking a math and a humanities? Or is that acceptable?

Extracurrics:
I’m a singer and I play piano. Will have an album out to submit to colleges as a supplement.
Prestigious world-traveling choir for a year, then moved states for my junior year.
Choir, acapella, and school musical (I was the lead) at my new school. Will have leadership positions in choir and acapella group next year.
I’m a writer. Have been writing for school newspaper for years, editor in chief of a publication at my new school. Also involved in other publications, writing and editing.
Very into politics. Have been involved in Model UN for years, now JSA as well (have a leadership position in the club). When I lived in my old state, I did the same community service bi-weekly for three years, now am Founder and President of “Fighting Hunger” club, also involved in work with Food Pantries.

Recommendations will be very strong-- one from a math teacher, another from my English teacher, a last one from my music director at school.

Thank you so much for taking the time to read this; I apologize for the length but really really appreciate any/all feedback. Have a wonderful day!

If you can get your Math score up, then you will have a shot. If not, then it may be a different story. Some of the LAC that you mentioned you will definitely have a shot at even with a low math score (only low for these schools, otherwise thats a great score).

Yea. Math is the easiest to get an 800 in. Doing so would significantly improve your SAT and ultimately your chances. I’d say you can get into any Ivy with your scores (plus the 800 in math). Your ECs are solid. Are you in any sports? Write good essays and you’re fine, then it’s up to the Ivy lottery.

Did you compose the music in the album?
If so, and the music is good (that is, more sophisticated than pop music), you will be accepted many places. I would suggest that you indicate music performance / composition as an intended major. If you are accepted, you will not be “forced” to major in music.
The “volunteer work at…” is so commonplace that it does not get taken seriously unless it points to a specific interest of yours. While many students are involved in writing (especially the school newspaper), it seems that you have done things outside of school. Having your work published in any form / media is generally considered the epitome of success because it verifies your writing ability and persistence.
Would ignore above remarks about participating in a sport. Since you can take 3 SAT IIs on test day, do US, Math II, and Lit.
