Reviews of professor Hang Ren

Rating: 1.0/5, difficulty: 4.0/5
I don't recommend Ren for OM 303. I'm sure there are better professors that don't teach as badly as he does. Granted this is his first semester at Mason, so maybe he'll understand how to teach college students that are generally taking this class because it's required. There's a lot of math in this class so be prepared. He plans on curving grades.

In all honesty, he's not the best lecturer and class attendance is mandatory. But he offers zoom sessions to go over practice homeworks that are nearly identical to the quizzes and graded homeworks. Quizzes are online with no lockdown browser too. Exams are in person, but he does a really good job at doing exam review where he posts in depth videos

To be honest, he is knowledgeable and his lecturer is easy but maybe because of his accent. There are 3 tests and bunch of quizzes but they are easy. U just review study guide and practice all those homework before exam.

Professor Ren's class was very straightforward. He has a heavy accent but you honestly get used to it as the semester goes by. He gave tons of hints for the quizzes and exams, and he also provided a generous curve for each exam. The graded homework assignments were a bit tough, but the questions were almost identical to the non-graded assignments

DO NOT TAKE HIM. His explanation is the worst, he is too fast, and you do not understand anything of what he says. sometimes the time period of the class ends, but still he wants to "explain" new materials quickly. in this class there r 2 midterms and 1 final, each midterm worth 27.5% of the grade which means if you don't do well in 1 ur screwed
