Selected Comments from Students:

​​

From Penn State: 

​

-- "Tianyi made it a great place to learn, and really made an effort to help students succeed through bonus office hours, answering questions, etc. he was really great and I look forward to more classes with him in the future."

​

-- "Professor Li always seemed to be happy and excited to teach. It was his first semester teaching and I think he handled his nerves well and did a great job adjusting. He was always willing to help and answer questions with homework assignments."

​

-- "I felt as if the class was executed very well. The in class lectures were very helpful when it comes to understanding the material that is introduced to you. Additionally, I do not normally attend office hours in most classes, however, the office hours, and the flexibility, were incredibly helpful. The exams were also, for the most part, similar to the homeworks which is a pleasant change compared to most other Econ courses."

​

-- "After classes, there were many students waiting in lines to ask him questions and he was always willing to help. During office hours, he always made sure that everyone understood the questions."

​

-- "He is very approachable and loves when students ask questions. He is always willing to hear his students out in times of need and willing to open office hours very last minute and take more time out of his day to help us as we take more time out of our day to learn his material. Very equal and just professor."

​

--"My learning experience in this course has been wonderful. Profesor Li is really good at his job and econ 412 is one of my favorite classes I’ve taken at Penn State. Although the material can be challenging, Prof. Li is always available to meet and incredibly helpful in this office hours. I’ve recommended this course and professor to all my econ friends."
