I could not understand the professor at all.

I loved his material. It is better to participate more in class, he enjoys it a lot so ask intuitive questions and he can help further your understanding.

Material is very challenging and I thought the professor did a very average job presenting it. There were not a ton of great resources if you had trouble understanding the lecture, as the textbook wasn't great and the way the topics were covered didn't seem to line up with the textbook or any online help. I felt like I just had to struggle through the lectures to try to understand, meaning that homework would take several hours. Then the midterm was pretty different from what we had been studying, so that was pretty frustrating. The final was easier and more straightforward, but overall this class was pretty draining and a ton of work. I thought Kim was a very average professor, and he did offer extra credit to help after everyone failed the midterm, so that was a nice plus. Don't think I would take it with him again, but I do think the material would be challenging under any prof so I don't think he was especially terrible.
