Great professor, homework can be extensive but tests are extremely easy. He provides ample examples in class similar to the questions seen on exams, just show up to the lectures, do the homework and you'll get a good grade.

Amazing professor who grades easy on exams and his lectures are good. Professor Yan is lenient on grading and also allows a cheat sheet on exams. Just do your homework and pay attention, and you should get the grade you want in the class.

Best math prof I have ever had. The lectures are always pretty clear and before every midterm he goes over everything that will be on it. All exams are pretty easy, homework can get difficult but you have unlimited chances and hw is weighted pretty heavily so definitely take all those chances. I would 100% take again thanks Yan
