Final exam was very difficult. Lectures were good and the homework assignments were high quality. He has an adjusted grading scale where passing is easy but getting an A is hard.

The lecture is clear and easy to understand, however, the final is getting very hard, much harder than last year. (In case everyone gets an A)

Yu Feng was a very reasonable, engaging professor and his lectures were super clear, so I was never confused even when it got a bit abstract. He went through the entirety of last quarter's final so that we feel prepared. CS162 is much, much easier than CS160. No complaints from me.

grade was determined by 5 homework assignments, with the professor and TA's seemingly making it up as the quarter went on. lectures had little relation in content or difficulty to the hw, generally covered material significantly simpler than the knowledge required for the homework. assignment instructions were often vague or hard to follow.

Great and passionate lecturer. Made the class very interesting and approachable!

I took this class in Fall 2021 and was worried because of the stories from past quarters with this professor. But everything was great: lectures were solid, homework was challenging but reasonable and interesting, and I learned a lot. Would recommend/take other classes with him

I took this course with hesitation, but it was absolutely great. Course has improved across the board. No complaints: the homework assignments were challenging but clear and fair, the professor and TAs were helpful during lectures, office hours, and outside of class. 10/10 Greatest professor redemption arc I've ever seen, kudos to Professor Feng.

Class was very straightfoward. 6 homework assignments for 100% of the grade. Homework gradescope results were available, so it's easy to know how you're doing in the class. Generous with late days as well, 10 days for the entire course. He has definitely heard the feedback and improved a lot. I highly recommend this professor now!

I took this class with worries, but it was one of the best CS classes I've taken at UCSB. The class materials are seriously interesting and helpful in other classes. I feel like I now have a better understanding in some of the features in programming languages. 6 hws sum up the total class grade with 10 free late days. No exams.

Yu Feng improved significantly. His class structure is now very fair. Some pros are that there are no exams, graded only on assignments, with 10 late days. I would save them mostly for hw4. TAs are always available and nice. Cons are lectures sometimes get tedious, TA's feedback occasionally too vague to be useful. BE SURE to use manual for hw.

Great enthusiastic professor, clear lectures. Only 6 programming assignments, which followed a bell curved shape in terms of difficulty, had 10 total late days you could use. Cares about his students, asking for feedback throughout the quarter. One of the best professors I've ever had, makes the difficult topic of PL approachable and interesting.

Great class. Lectures were interesting and clear. No exams, just programming assignments, which were very fair. The professor and the TAs were friendly and helpful.
