Reviews of professor Chuanren (Charles) Liu

Rating: 4.0/5, difficulty: 3.0/5
He might have an accent that is hard to hear sometimes. Other than that, he is super nice, well prepared for the class and tries to make students actually learn something. I have problem submitting the homework so it was turned in late. I explained to him and he still gave me full credit.

First quarter of MS Business Analytics program, which I went in to without a programming background and with a weak stat background. We used R and he, along with another class, opened up a Pandora's box of programming language learning ability for me. Great guy and he cares His preparation, materials, and structure blew me away.

horrible professor, bad at teaching, decided to give everyone bad grades on his last term before leaving drexel announced "we won't have a final because everyone did well on midterm" while the average for the midterm was C+ what a shame

Second class with Charles -had developed a relationship with him by then-shows you the kind of prof/adviser he is. Gave us full autonomy in data set choice for project that applied supervised learning techniques to create business insights and reco's. After course (+ after he had left faculty) he helped my team submit our paper to a conference
