Typical gpa contract once admitted?

I was wondering what the usual contract and conditions are in order to not get rescinded for Berkeley and UCLA. Is it typically just maintaining a 3.0 gpa? Do they care if you get a grade like a B- in a class which would be 2.7 gpa as long as the overall gpa from that quarter is still fine?

Each provisional is unique. A standard is alert us if you get a D or two Cs but some are way stricter. It may tell you to maintain a 3.0 or even a 3.2 or have certain grades for certain courses (never As but often Bs). It really depends.
