Reviews of professor Qian Cheng

Rating: 2.0/5, difficulty: 5.0/5
He was very disrespectful to students and refused to work with us. The content was okay but he couldn't explain things well. Also never felt like I could ask questions about the course content. Study guide was written very poorly and nothing like the actual exam

Professor Cheng is awful. He is inaccessible during or outside of class, condescending towards students, and on top of all that cannot convey the material in a coherent manner. Worst professor I've had at UNC by a long shot, I mean it seriously isn't even close. If you see any positive review on this page, just know theres a 99% change he wrote it.

this guys terrible. barely escaped class with an A-. I taught myself the entire course, as he did not teach at all. I have no idea if he will teach STOR 155 (which is supposed to not be a hard class but he makes it so hard for no reason) but if he is, DO NOT take him. He will laugh at you when you fail his midterms

Its his first semester teaching so theres still room for improvements. Overall, caring guy, very lenient grader, gives a lot of partial credit on tests and some extra credit if you show up. Bombed my 2nd midterm (got lowest grade in class I think) but still ended up with an A because final and homework weigh 30% each.
