Will my admission be revoked?

When I applied, my GPA was 3.479 weighted. First quarter of senior year, it bumped up to 3.61, but I messed up big time in the second quarter, and I'll probably end up with something around 3.33. I also didn't do great on midterms. Do you think there's a chance they might revoke my admission? I got in during the regular decision round and chose undecided.

I don’t think it should affect the admission decision they gave you, since the decision was not just made on the basis of your GPA. And as you might know they consider many other factors before giving a decision.
