Reviews of professor Gang Liu

Rating: 5.0/5, difficulty: 3.0/5
Dr. Liu is charismatic and professional at the same time; he is very enthusiastic about the content he teaches, demonstrates clear concern for the learning of his students, and is organized and consistent with his lectures.

I failed his class the first time. I took it again and passed with a B. He is willing to help if you show up to his office hours. He is really nice. This class is a lot of work so you need to put in the time in order to pass.

Dr. Liu is the worst instructor I've had to date. He makes his exams much harder than necessary and much harder than what he prepares for in lecture. He hardly answers questions during lecture, and his grading is strict. Even if you understand the material well, you may not do well on the exams because there's no set expectations for difficulty.

Dr. Liu is the best choice for ME 2010. He doesn't do the best with questions during class but neither does Dr. Joseph. He really does care about his students. I highly recommend going to his office hours. He fully explains everything in class which is crucial in 2010. Accent isn't a problem. His final is a tad bit more unpredictable than Joseph's.

Dr. Liu was very helpful outside of class. He always offered extra office hours to answer questions and was very accessible by email. ME 2010 is notoriously hard and the material is not always clear in class but if you go to office hours he will do his best to help you understand the material.

This professor is terrible at answering questions in class and gets frustrated with students when they ask questions. He is an extremely tough grader and provides NO practice exams or practice problems to prepare for exams. I have no idea how a great engineering department at Clemson can allow professors like this to teach. DO NOT TAKE THIS PROF

Doc Liu is a solid prof to have, he can get rambly sometimes during his lectures but he genuinely wants his students to succeed and he helps you if he sees you working hard. The homework isn't overbearing but takes time. His tests are very reasonable and don't expect you to do anything incredibly specific or out of the ordinary.

Dr. Lui is the best option for this class. If you have any questions, big or small, he will give you answers no matter what and make sure you understand them. Lectures are tough and long, but that's the way things go. There is an accent barrier, but it shouldn't take more than a few days to get past it. I recommend using his office hours.
