Let’s back up some from “how to get in” to “why would you want to get in?”. It’s understandable that a HS student will have a favorite college(s) choice, for whatever reasons, but be careful about seeing admission as a prize to be won, when it’s actually more about “good fit” vs “poor fit”.
Attending a school at which you would constantly be struggling to achieve even median performance isn’t much of a way to spend four years. Then on the back end nearing graduation, it will become apparent that employers aren’t generally going to be interested in someone with poor grades from a good school… and grad schools even less so.
The good news is you that have demonstrated yourself to be an intelligent and capable student. You will almost certainly be admitted to selective or even very selective colleges. Then it’s just a matter of choosing the right one, the right major, and working however hard you decide to work (the one real determinant of success, and it can be accomplished most anywhere).
