Rating: 1.0/5, difficulty: 5.0/5
Never completes his example problems in class and teaches like the class already know the material. I learned more by skipping class and watching YouTube videos. Nothing he said helps and he is incapable of explaining things in an way that makes sense.

Great professor. Def bods can be a little rough sometimes, but he is good at explaining the concepts and will go over them again if you ask questions. Would take again 10/10. The homework is from the most recent ed. of the textbook, but I just checked it out of the library when I needed it, and I relied on his lectures and slides for the material.

He was nice and very caring about the students. He provided multiple office hours throughout the semester and he gave really generous partial credits, especially for the final. Tests were three attempts each and they are from the online textbook so if you do most of the textbook questions, you could get the same question for the exam.

Sweet, funny dude. Terrible lectures involving unclear steps, undefined variables, and half-finished problems. But this is overshadowed by his wonderfully easy tests: 3 attempts for 3 textbook site HW questions + crib sheet + generous partial credit. When confused, the internet + the TAs can be your friend.
Recommended.

Any shortcomings are forgiven by how easy his exams are. You get 3 attempts per question from the same question bank as your homework. However, I'd still recommend going to lectures as he gives many useful tips on solving problems efficiently and does example problems.
