Labs are very time consuming especially if you are taking this class and it isn't required for your major. Very nice, and genuinely seems to care about his students and the subject he's teaching.

lowkenuniley a great guy, super nice and passionate. I rushed through labs and homework so I missed easy points there but def don't make the same mistake. Midterms and Finals are presuamble curved so the avergae is at least a B. I was able to get an A on the midterm and B+ on final, they didn't feel exccesively hard just throuhgly study

LOVE THIS MAN. While lectures are not mandatory and are recorded, please go, as he genuinely deserves the audience. RECOMMENDATIONS: I got an A by getting basically 100% in lab/HW, but don't stress: I got mid Bs on midterm and final and he rounded. Definitely do past midterms/finals. For the final, I did well because I memorized the algorithms.

Prof Wang was super kind and engaging. In-person midterm and final were pretty standard in comparison to other cs classes. Lectures and sections weren't mandatory but I would recommend going.

Professor Wang does a phenomenal job at explaining the course content in a way that is easy to follow. Every lecture is recorded and posted, but I would still recommend attending. The exams are structured as well as any CS test can be. You'll do well on them if you want to actually learn, not just get the work done. Labs are challenging, yet fun.

Amazing professor, responds very fast on Piazza and seems to really care about students. Labs range from time-consuming to frustrating as the autograder gives no feedback on what you're doing wrong. The midterm and final exams make up 70% of the total grade, so be prepared to study concepts heavily, not just memorize.

If you're in this class, good luck. Wang is a good teacher, explains things pretty well and has organized lectures. Definitely start labs early and go to office hours, some of the labs are very difficult and they're autograded so sometimes you don't even know what you're doing wrong. Test are the worst thing I've ever experienced, study hard.

Wang is an exceptional prof. He's not only passionate abt what he's teaching, but also cares deeply for students. His class is very organized, his lectures are effective, and he lays out expectations of the course very clearly. This is not an easy class, but there couldn't have been anyone else who would have taught it better

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.

Homework was easy but there was a decent amount of it (for the first few weeks, tones down in the latter third). Quizzes are a little harshly graded but overall very clear in expectations and content for the class.

He is probably the best lecturer I've had so far. Very clear and easy to understand, very caring and nice. He doesn't use Canvas and you have to buy the online textbook, but is easy to contact and gives good feedback. Quizzes every 2 weeks that range in difficulty but aren't awful. Final wasn't too bad. Absolutely take him if you have the option.
