**Comment:** Personally, I think these ratings are way too low. Looking back, I liked him because he used common sense. Professor Chen could have easily spent lectures going over mathematical details or asked us to prove things that are essentially just exercises with little application. Or, he could have been overly concerned with abstract concepts that we were really not mature enough to *truly* understand in an intro class...but he wasn't. He was concerned that we understood conservation of energy, conservation of mass, and know how basic steady-state systems work.
Was he tough? Eh.... haha. Kinda. The averages were about 20/30 for each quiz (5 of them). There were no "midterms." I'm sure everyone thought the final was hard......... but what else is new?
P.S. I'm not sure if this was intended, but some of the "numbers" he threw out in lecture tended to be answers to quiz problems (i.e. if he says something is 30% efficient, then you might end up with an answer of 28.9% efficiency). The mysteries of Cal.

**Comment:** Took 107 with Chen. He's a nice guy and all, but he just doesn't have a presence in the classroom. That being said, he's a fairly good teacher and works hard to get the concepts of DoE across.
