Pham is an amazing professor. 14C is difficult but Pham made it very easy to learn and made the material interesting as well.

Pham is a very good lecturer, however I would say that his lectures are not as indicative of the difficulty of the tests. I found his homework sets to be much more indicative of the difficulty. Additionally, I found that he did not give helpful responses to questions to learn the material. I much preferred the TAs and LAs. He tends to be a bit impatient and does not take the time to thoughtfully consider your question (however I did notice his responses tend to be a little better on the discussion board). Overall, I would take again but be prepared to put in a lot of extra work and do not waste your time going to his office hours.
