Will i get rescinded (grades provided)?

The rules for the UC system state that you must maintain a 3.0 and have at least a C in each cl to maintain your spot. If your GPA does drop to a 2.8 you will lose your admission. You should at this point improve your grades as much as possible and if necessary contact the UCI admissions office to see if there's anything you can do. It's a harsh reality but every year there are students who get their admissions rescinded because they didn't maintain the minimum GPA.
