ALOT of kids at the University of California schools cannot graduate in 4 years due to budget cuts. We had a babysitter at Berkeley who was really bright and driven, pre-med, etc. She waited 2 years to get into Organic Chemistry because it was full! It's not that she forgot to sign up or was lazy, it was full. She would audit the class and the lab for 2 weeks, sitting in the aisle of the auditorium where lectures were given, and she wouldn't get in.
