Will Hamilton/ any other mini Ivy League accept my gpa?

Mind my title, I hope you understand the range I’m looking for

I’m a.rising junior and I’m proud of what I’ve accomplished..

But my cgpa is low. My freshman year really pulled down my grades. In sophomore I improved… now it’s a 3.5

Junior year, assuming I get straights A’s or wtv let’s say I end up with a 3.7 at the end of that year. Idk how it works but would t20s accept it? I know SAT scores and stuff are also important but I’m talking about my gp A 3.7 is pretty low compared to other applicants but it gave me hope cuz I know someone who got accepted to Columbia with a 3.6 (?) gpa or so among other things

I’m new to this whole thing, it’s kinda confusing b it I became self aware of college much later that I was supposed to, my school is different from others as college is something that’s rarely spoken about even for juniors and seniors_ I have a different case tho
