Reviews of professor Liang Xu

Rating: 1.0/5, difficulty: 4.0/5
I'm not sure if this professor actually understands what he is teaching or if he is able to teach this course effectively. He goes over eat examples in class and then puts long, difficult questions on tests. You will be lucky to get any points from the bonus projects he assigns as he didn't even grade our final bonus project. Will never take again!

You actually have to apply yourself in his course but he really cares for his students and give multiple opportunities for a better grade.

Professor Xu is a wonderful teacher. He takes time to do numerous example problems, will address specific questions, and gives different ways to earn points. There was no cumulative exam in Operations Management and he offered 3 bonus opportunities for 5% total added onto the final grade. I also took his online Business Analytics 2 class.

Really nice professor, does everything he can to help you out if you ask. Took online class, it wasn't easy but I've had way worse experiences.

Had him for two classes one in persona and one online. I think online was better with him. Lots of time in person I'd get lost with his lectures especially if using excel. He cares about his students, will help you up your grade. Drops lowest quiz usually to help. sometimes allows open notes for tests. Attendance required in person.

He acts like he is better than you with his attitude. In class examples are no where near the difficulty of the tests.

Not much extra credit so don't rely on that to help your grade. Homework assignments you only have two attempts per question to get it right. Quizzes you have two attempts to take. Quizzes and Exams are timed and can be stressful with all the math. Very easy to get lost and confused. Everything is in Pearson with set dates.
