Chance for Being Rescinded?

My grade dropped from a 98 mid year to 78 final. I know that’s a really big jump and all, but’s its in a class unrelated to my major and I have all As otherwise. School is an Ivy League but I’m worried what will happen.

3 f’s to avoid

Failing grades
Felonies
F ups on social media

1 c won’t move the dial. Maybe a request for a reason. Probably not even that

No Ds, Fs or Felonies. You’re fine.
