Reviews of professor Siming He

Rating: 5.0/5, difficulty: 4.0/5
Dr. He is special, perhaps the best professor for ordinary and partial differential equations at Duke. Not only is he incredibly sweet and genuine, but he also knows ODEs/PDEs so well and can answer any questions them precisely and clearly. Dr. He spent hours of his time meeting with me 1:1 to ensure I understood the material. EXCEPTIONAL.

Words cannot describe this angel of a man. He is such a thorough teacher and I have really enjoyed this math class. 353 has become my favorite math class at Duke thanks to him.

An absolute god. It was such a fun semester learning from Dr. He. Wish I could take a class with him every year here at Duke!

Professor He is honestly extremely nice and considerate. There is a language barrier but that does not impact the class. His lectures can be long and boring but he is respectable and is a pretty strong teacher. Grading criteria is a little iffy tho, but a good math teacher.

He's an amazing professor. He was very caring and his lectures were very clear. Homework takes some time, but he makes his exams easier than the hw.

By far my favorite math professor I have had at Duke. He really cares that you learn the subject and is super accessible outside of class, especially before exams. The TAs who grade the homework can be super lenient or tough, but at least He grades the exams and grades fairly.

Prof He is a really nice guy and he'll answer any questions you may have. His lectures were kinda long and I had a hard time paying attention. His lectures were structured but sometimes it was still a bit hard to follow. This class has a lot of difficult homework so make sure you give yourself time to do it.

By far the best math prof I've had at Duke. Explains things really well, good at providing lots of examples and very nice! Lays out what will be on exams so you know how to prepare and exams are overall very reasonable and doable. I think homework was graded on completion. Overall 10/10, definitely try to get in his section.

Very good, straightforward lecturer. He introduces theorems, proves them, and provides examples. His exams are very similar to the homework and lectures, with perhaps a few extra tricks (they're also a bit long). His lectures can be slightly tedious, but that's to be expected in a differential equations course. Homework is long, but necessary.

Give up all hope of learning anything from this professor. Dr. He is a nice guy but is confused by his own course material with half of his answer keys to the tests being "I don't know" (at least he's honest). Needs students to constantly correct his mistakes. Learned everything from the textbook and now might actually know more than the professor.
