What grades do I have to get in order to avoid getting my acceptance rescinded?

@ucbalumnus I haven’t seen a school that explicitly stated a minimum GPA other than not to get a grade lower than a C and/or maintain your academic performance. I think that if I do get all Bs this semester, I’d end up with a at least a 3.7. My guess is that this is unlikely to trigger anything. But, I want to know your thoughts.
