I am not exaggerating when I say he is by far the worst professor I have ever had in 4 years of college, and probably one of the worst humans I have ever had to interact with in my entire life. There are hard professors sure, but he is more of a billeting jerk who tries to make students feel stupid compared to him.

He's very stimulating in lecture, and frequently asks the audience questions which enhances attention and learning (in my opinion). His homeworks can be quite long, and your research skills shouldwill be definitely sharpened, but the questions are very interesting. Tests are pretty fair.

A beautiful series on drug design. Entertaining lectures, laid back classroom setting, chill homework assignments, crucial feedback. Kahn does everything that other professors try to do. Most professors suck, but Kahn is an exception. It is clear that he has been in academia his whole life because he has perfected teaching. Very enjoyable.

The coursework is manageable, but be ready to put in the time on assignments. Attending lectures is crucial - you'll get a lot more out of the class that way. For study prep, Unstuck study and the free textbook were super helpful.

Prof Kahn was a great first impression of UCSB for me as a transfer; always asking the class for ways he could improve our quality of learning and he implemented them. Grading was fair and there were lots of ways to earn easy points, like vocab pop quizzes or extra credit. He also likes to recycle questions sometimes on exams/homeworks.

Truly one of the best teachers I've had at UCSB. I was worried about taking this class because I've heard he's very tough, but he's literally so sweet. He cares so much about his students individually. He stayed late in his office to help me with homework, slowed the course down, and asked us what he could do to improve his tests and listened 10/10
