I did very well in this class but this was not because of the professors (Pang, Yeh). The reason for this is that I studied a lot and was mostly lucky that I was able to read the mind of the person who wrote the test and guess the answer on the exam. Yeh only teaches the first three weeks, which is straight forward. Then she will leave and you will never get a chance to ask her any questions about the topic, because she will not have any office hours. After week 3 Benison Pang starts teaching and then hell starts. Pang just reads off the lectures very fast, so fast that the class most of the time ends early. He is unable to explain most of the topics, whenever you ask him a question he is never sure. He even made a mistake during the final review and it was not until five minutes had past that a student who knew the correct answer had to correct him, then he was like oh yeah you are right. Pang does not know enough to teach this class, for instance he was unable to explain some lecture slides, he would say 'oh I am not sure about this' or something similar. You will never find out why you lost points on the exam, exams are complete bullshit. They will test you on questions that you have never seen before. Like the previous person who wrote a review said " Pang never went over a bootstrapping problem during lecture like the one he gave on the final". Pang would not be able able to do the final, he is that useless and uneducated. Pang & Yeh do not care about their students, they seem to just want to pass time during office hours and get paid. You never know if you will be in a class that they decide to make extremely hard just because too many people have gotten As the quarter before you. Never ever take these two professors, save yourself the headache and stress.
