I spent a summer at Berkley coming from as liberal an institution as there is. The biggest difference that really affected me was the professor stood up during exams and shouted out every five minutes that five minutes had gone by. Where I went to school, professors weren't allowed in the room during exams. Even timed exams. I don't know, but the whole shouting out the time and stuff really sucked and did not help me learn calculus. It just distracted me and made me play games with time rather than with equations. Different environments suit different students.
