Usually they tell you what grades you need to get to maintain your admission. For UC's (correct me if I'm wrong) it's a C or better in all classes and at least a 2.0 GPA. That being said, I'm not sure whether that holds true. You never know with the competition these days.
if you've already been accepted, just make sure you stay above the minimum grade requirement (check UCD's website for most updated info) and you'll be fine. don't worry too much...they already want you...
