Reviews of professor Yun Wang

Rating: 3.0/5, difficulty: 2.0/5
Yun Wang sucks at lecturing but you can tell he cares about at least trying to interest students in renewable energy, which I respect. Gives out mostly As and Bs and the class projects follow the ideology of “learning is fun”. I personally thought the paper was a good way of learning about PEMFC though. Kind of a meme class overall

Disorganized/useless lectures that are useless for the actual labs, which are actually pretty hard and ask for many questions that have 0 references provided. TA grading is also inconsistent and arbitrary.

Nice guy who tries to engage with the class, but the teaching is meh and class is a mess. Labs ask questions that not even the 10th page of google can answer. Lab grading is also strict, random and inconsistent.

This class difficult mostly because of the horrific teaching and grading. The lab report grade averages are frequently around 40%, but the worst part is why; the grading rubrics have things on there the assignments never mention, so you lose massive points for things that aren't even asked on the report. It's an unfair nightmare of a class.

Lecs. are not engaging and poorly run. Often unprepared. Just read the textbook, which itself is good material. HW are often vague and unclear. Constantly have to email him for clarification. When he can't explain something in the text, his default response is that the textbook has a lot of typos. Says "So again" at the beg. of every sentence.

Took his 117. I'd rather just read the textbook, and that's what I did for half of the semester. His lectures were useless, yet homework was super difficult. he teaches you 1+1 during lecture and ask you to do derivatives for homework. "so again, so again", endless "so again" after every word he says.

He cares if you pass and encourages you if you are not passing and helps you. You won't need to buy the book for the class, he teaches from the book on powerpoint. He's a wonderful teacher and very helpful, the class can be an easy A/B/C if you do good on test(homework) and exams.

Dr Wang is bright but suffers immensely from a language barrier, so it's often hard to understand him when he speaks and writes. Often, you'll find yourself doing the same work on multiple assignments. It's nice to reinforce concepts, but it's very boring and not worth the money. And with group projects each week, it can get frustrating fast...

Most disorganized class I've ever taken. Wang & his TAs put problems on the reports that you don't actually have to answer, and not say anything about it. So students spend hours doing something, then right before the due date have to redo most of their work. The grading is ridiculous. They mark off for things they never specifically asked for.
