Chances at getting matched to top schools through questbridge with weak ECs?

im a questbridge finalist and I was wondering if I have a practical chance at getting matched to these hella selective schools, because if not I need to start planning for RegDecision

ranking:
Princeton
Yale
MIT
Uchicago
Columbia

probably going to apply to caltech, rice, pomona, and maybe harvey mudd and harvard reg decision

stats:
-SAT1: 1540 (760 rw & 780math)
-SAT Math2: 690
-SAT Physics: 740
-ACT: 32 then a 33, highest scores are 35english, 35math, 32 reading, 34 science, but im contemplating reporting these because its expensive and i think my sat1 is good enough
-GPA: 4.0 unweighted, my school doesnt calc weighted but i did it myself and it came out to be ~4.7, not sure if its 100pct right
-class rank: 8/602, 101.6 cumulative
-AP: 5s in Human geography, European history, Lang, World history, Seminar, calc ab, us history, 4 in physics 1(im human :/)

senior courses:
AP Chem
AP Physics C
AP Macroeconomics
AP US government and politics
AP literature
AP Calculus BC
AP Research

achievements and extracurriculars (pretty weak, will def hold me back):
-National AP Scholar
-Questbridge College prep scholar and finalist
-Georgia certificate of merit
-AP seminar student of the year
-JV Quiz Bowl captain (9th)
-cello player 6th-11th grade, first chair a couple times
-AV technician volunteer at church since mid junior year
-science bowl (pretty big role as one of the 2 seniors on the team, best player on the team since ive taken full years physics and chem)

other info:
-I changed high schools between freshman and sophomore year which was crazy hard on me, but its really no excuse for low involvement in school clubs

-Both my parents were born and raised in africa and immigrated, so im an URM

-My sister wasnt matched but is currently going to uchicago through questbridge reg decision. can anyone tell me how important this is?

-Prospective majors are astrophysics or international affairs

-My letters of rec are probably very good, ive had the teachers multiple times nd they all think im the second coming of jesus or something, so theyll prolly exaggerate how good of a student i am which is always good

-All of my writing is basically about my background and how its led to my interests, or occasionally cool movies/shows/lectures ive watched or books ive read. I googled some stuff about college essays and apparently readers like it when everythings super consistent/full circle with all your other writing, so i tried doing that and i think it worked out pretty well

EDIT: forgot to mention that I already applied to Georgia tech and UGA, so ive got some safeties in the back

Bump!

you have strong chances. im also a qb prep scholar and finalist. chance me back and good luck!
