The Honors program at UCS would give you much smaller classes and far more faculty attention than you’d get in your lower-division classes at Cal. Berkeley is an excellent school, but there’s a lot of competition for resources - difficulty getting into classes, housing crunch, lots of being taught by grad students. For similar $ I would consider the Thematic Option Honors Program a better value and educational experience. At Berkeley you’d be paying for the name but waiting in line for UCB to deliver on its reputation. JMHO.
