STRESS. Dr Yang is the hardest teacher I've ever had, but at the end of the course I felt confident that I knew the material. You HAVE to follow along with lectures & if you don't study, you won't pass. Open ended test questions are never as easy as the examples in class & he isn't a fan of partial credit. Stay ahead, try hard & study before class.

Grade: A-
Dec 23, 2025

I got an A- in the class and worked incredibly hard to get there and he purposely dipped numerous lab grades so I wouldn't meet the requirement and now I have to retake the class and spend more more. Not a good person doesn't respond to emails and is overall disrespectful and inconsiderate. I don't know why he's a prof because it isn't for him.
