<p>If 40-50 students seem like a large class to you, I’d choose Tufts or CMU where you least likely to encounter such classes. At UCB, many first year classes will have several hundreds students and some will be close to 1,000.
Classes with fewer than 20 students: CLU 68%, Tufts 69%, UCB: not reported
Classes with more than 40 students: CLU 14% (including 4% at 100 or more), Tufts 9% (including 2% 100 or more)</p>
