Information About Teacher

Professor Zhou is, overall, a very good teacher. 
Zhou has a vary clear and efficient teaching style. Zhou makes DE easy to understand by using clear examples which are easy to follow. 
Zhou assigns homework and collects it regularly.
Zhou's exams follow both the homework and his notes. His exams are fairly difficult but are usually no harder than the homework (no trick questions).
Although the DE book is required, it is not used in class, Zhou simply assigns homework from it.
