Chance me for Harvard + Stanford? (Classics! + UK international applicant)

Hi - international applicant here (UK):

Don’t have a GPA, but test scores:
GCSEs - 10As, 2As (Best in my school, which is selective)
A-levels (predicted) - 2A
, 2As (I’m taking Maths, Physics, Latin and English Lit)
SAT (New) - 1470; 760 RW, 710 M (oops lol); Essay 6/6/8 (also oops, but I’m too poor to retake)
SAT IIs: 780 on Lit, and 770 on Latin

Awards:
Foyle young poet of the year (International, if you haven’t heard of it)
Top prizes in a few national poetry competitions (not listed for privacy); huge prizes/prestige in the UK, but not sure if admissions will have heard of them?
A couple of Oxbridge essay prize commendations (English lit).
A local badminton prize (should I put this on?)

ECs:
Writing (see above ahaha); published in some paying(!) ‘adult’ journals (2%< acceptance rate), but might be vaguely obscure to an international audience.
Showroom manager (pays badly, but is interesting and fairly fun)
Prose editor at a (fairly) small litmag, but it takes up a lot of hours every week
I run the French club at my school and act as a STEM mentor
I also tutor maths, but that’s really generic.
(This doesn’t seem very long; is that going to be an issue?)

I’m a prospective CompLit/Classics major, though I’m leaning towards classics. I’ve already written a(vaguely ranty) niche-y commonapp/supplement essay on obscure latin texts and another kinda satirical one (partly in Latin! - with a translation, ofc); will that be enough?

Also, does anyone have any experience with the classics departments at these schools? (Everything I know is through the websites + reading the Loeb classics).

With that SAT score, you’re gonna have a tough time. You need to really sell your writing skills. Since you’re a gilded writer already, the essays might be in your favor. Good luck!

Ah, can anyone else help? Also, how strict are the guidelines for the SAT? - only the middle 50% is given

Whoa those GCSE results are amazing! (I’m also uk)
The 1470 is only the 25th percentile though.

Try to raise SAT, after that it’ll be random.
