Reviews of professor Long Jiang

Rating: 4.0/5, difficulty: 2.0/5
I had Long for Mechanics of Composite Materials. He was a really good prof. He explained things well and used multiple methods to teach including lectures, videos, and in-lab manufacturing demos. However, the class was almost too easy (especially for a graduate course) and I wish we had covered more.

Long creates high quality lectures in his online section. He also teaches the material well. 

I walked away from his class with a strong understanding of Mechanics of Mateirals. 

If you want to get by without doing much work you probably could but expect a B or C. 

Tough final but he prepares you for it. 

Very accessible and caring.

The best ME223 teacher. The classes are very informative, you have notes that are laid out well and then step by step examples. Concise and fair grader.

The exams are extremely DIFFICULT! You'll study the notes from lecture, homework, and book only to find out that the exam question is way more complex. Nothing will prepare you for the exam. Jiang/Nazari even took a question from a Machine Design textbook and put it on the final exam?!? 6 minute, out of nowhere pop quizzes also.
