Reviews of professor Xifeng Jin

Rating: 5.0/5, difficulty: 4.0/5
I took Calculus with Professor Jin, he is very kind and inspiring person, he makes complex issues clear with simple examples. He may have a little accent but it did not affect my understanding of the course. Will definitely take his course again

Very hard to understand his thick accent. Whole lecture is just him copying examples from textbook. Attending to lectures did not really help whatsoever. You'll end up teaching yourself the material.

He is helpful and a good person however he is not a good professor. He speaks very low and you can barely hear him. Just copies straight out of the textbook. Your grade is made up of only 4 tests & 4 quizzes (no final). He gives HW but it is not graded, I recommend doing it though. His tests are pretty easy and he curves the final letter grade.

Xifeng is a great professor; I had him for his first time teaching. He did well even though most of the class was not fond of him. He is very informative and will answer any questions in class. Xifeng is sweet, and wants his students to succeed. He gives practice exams which are similar to the exams, ungraded homework, and big curves. StudyEasy A.

I genuinely like Professor Xifeng. He is a nice man and his intentions are good, I just did not find his lectures helped me learn. He is difficult to hear and his lectures consist of him recopying notes onto the board. Luckily he is a fairly easy grader and provides practice tests that are practically identical to the real ones.

Math is difficult. But he has a big curve. In addition, he has a little homework. If you have any question or suggestion, he will listen.

Coming into this class I never took calculus before. His lectures consist of him copying notes onto the board. I found his lectures to be somewhat useful, but really what helped me was the small group sessions offered by the engineering school. His tests are very easy and as long as you do the homework it is an easy A course.

The worst professor I have ever had. He "taught" directly out of the textbook, didn't explain himself, and frequently misgraded assignments.

If you have Professor Jin, good luck. You will need it. Be prepared to teach yourself calculus.

It's really hard to hear him as he refuses to speak any louder and he can be difficult to understand with his accent.
