Worried about rescinding

I was accepted to MSU a few months back but now I’m very, very worried. When they accepted me, I had a 3.7 GPA and a 24 on the ACT.

This year though, I decided to take AP Calculus. I have done everything I could and taken every opportunity to raise my grade in this class however for the entire year I’ve had a steady D. Next to that D, I have all A’s. It’s more of me not understanding the material rather than senioritis. Before this year I had a majority of A’s with a two B’s thrown in for my entire high school career (minus one semester where I suffered from some issues, this was explained to them). I was also dual-enrolled in a class at U of M Flint that I had a D in but the credits don’t transfer over anyways. My GPA IS still a 3.7.

I’m terrified of what could happen because MSU has been my dream since I was younger. Is there a big possibility my acceptance will be revoked?

chill dont worry
