“Fortunately, there exist what I feel is the holy grail in engineering, schools with good toys, complete curricula, smaller classes, irrespective of the overall university size, and little use of TAs. Lehigh, Rose-Hulman, HMC, WPI, Case, RPI, and Cal Poly are all strong examples.”
It may depend on definition of large class sizes, but Case, RPI, Cal Poly have large (like a few hundred for the lecture) in freshman classes and use TAs for the problem set classes, which are much smaller.
