Great lectures for a CS class, you can really learn stuff from it. The final was a bit harder than midterm, it's better to study well before hand. Homeworks are not that bad but labs are quite hard, start them early and go to office hours. Understand homeworks, labs, and lecutres, and you will do good in the class. Pretty good teacher overall.

I took his class for CS9, and honestly a great overall experience. He is very good at making hard concepts make sense. He is always very professional, and his github for the course has all you would ever need and more to succeed in his class. He posts all of his recorded lectures which is very awesome!

Tough class with the new syllabus (70% of your grade determined by written exams) There are plenty of office hours for help on labs/hw due every week. Professor Wang knows his stuff, so is very important to attend lecture/watch recordings and read the textbook to pass the class, since it is very conceptual and there was only a small curve.

I took Professor Wang for CMPSC9 for Python, and he is great. There are two exams (midterm and final) each worth 35% each. I recommend studying lecture notes and reading the textbook and making sure to memorize coding algorithms as well as theoretical stuff to get a good score on the tests which are pretty important to get an A in the class.

Extremely organized professor. Lectures are engaging and well organized, and you can access recordings and summaries of them online. He truly is one of the most fair professors at UCSB, everything in the homeworks, labs, and tests are very do-able as long as you study the materials and pay attention in lecture.

Best professor ever. Really helpful lectures and enjoys answering questions in class. Perfect reasonable amount of homework. GOAT!! I'm going to miss him
