Help with grades

So i had a bad freshman year , but literally all of my other years are fine.

these are the grades :- 9th grade - 83
10th grade :- 98.6 (boards)

9th and 10th grade were in cbse

11th grade :- AS - AAAA

12th grade :- predicted - A*A*A*A

SAT :- taken 1 time 1590 (M-800)

APS :- Calc BC, CSP, Macroeconomics, AP Physics, AP Chemistry (5's on all, school dosent offer them, taken privately and self studied)

I live In India .

My preferred major for colleges in the US would be CS or Math+CS or purely Math

My college listg goes like this : UIUC (top choice for cs realistically), Umisch , purdue, gtech (prolly a reach for me), Harvey Mudd (idk much about how mudd looks for me, but was going to apply math+CS), Northwestern , umd, all ivies (Columbia and cornell are my preferences as they are *relatively* easier to get into and cornell has the best cs program apart from princeton and i just like columbia), berkeley(eecs, ), ucla (second choice eecs, first preference cs),
