Reviews of professor Jianzhen Liu

Rating: 4.0/5, difficulty: 3.0/5
Not much, I actually took him for CIS 160. His class is okay, but a little outdated.

Rating: 1.0/5, difficulty: 5.0/5
Very disorganized and is very intelligent. Just bad at teaching and helping if you don't understand. He doesn't give feedback or respond to emails. I wouldn't recommend him as a professor.

This teach spoke very poor English and is very hard to understand so if you have him good luck.
