Super helpful and genuine! Made sure he was explaining things throughly every class!
Course was challenging yet fun. Zhifeng helped A LOT.
I liked that he was willing to answer any and all questions, even if they were elementary topics in the course. Gave good explanations of the material and motivated students to do their best work.
I liked that Zhifeng was very helpful with preparing for quizzes. He often went over effective examples to clarify concepts before we took our quizzes.
He devoted time in class to review before taking the quiz which was very helpful. He also made sure to answer questions thoroughly and multiple times if needed.
Zhifeng was very patient with us all, and every meeting we had, he reviewed course material clearly and at a manageable pace. He was also very understanding if I happened to be struggling that day.
kindness and knowledgeable.
I like how he asks us for our questions then gives us practice problems to work out based on our questions.
He helped lay out what would be on the exam so I knew what to study.
He seemed very knowledgeable about the topic and I think he did a good job visually showing the steps of the calculation.
I liked how much he enjoyed answering our questions and clarifying topics that we did not understand during lecture. I liked how hard he tried, he wasn’t exactly the best at explaining topic but he would try very hard to make sure us students knew what he was talking about and asked many times if he was explaining things clearly.
