Reviews of professor Jong Ryu

Rating: 5.0/5, difficulty: 3.0/5
Overall good professor, recommend him for solids. The midterms aren't that difficult, but they are only a few questions long so each question counts for a decent number of points. Final was substantially harder than the midterms - I got As on all the midterms and a C on the final. Lectures were organized, similar to the book, and easy to follow.

Dr. Ryu is a great choice for 214. His layout of the course is amazing and provides you with all the materials to be successful (LOTS of example problems). Homeworks can sometimes be a little hard, but he is always willing to help. He's also a really nice guy, if you have the chance to take him for 214 do so!

Goes through material way too fast and takes breaks to rest instead of just a normal, understandable place. Tests are difficult and too long for the allotted time. Homework is scrutinized for small errors and graded hard. And know that arctan(infinity)pi/2 because apparently that's worth about 10% of your course grade, despite no mention in class

Dr. Ryu is probably tied for my least favorite professor that I have had. I found his lectures to be long and confusing as well as the problem sheets that he gives to "help". The final was worth an absurd amount of our grade and sometimes he was rude to students and wouldn't help them if he thought what they were struggling with was too simple/easy

First day + syllabus: homeworks graded on effort. Later, he takes points off of HW w/o a rubric  + no feedback. He regularly violates FERPA (posting student work). He fell asleep through a majority of the final project presentations and asked irrelevant questions after each final presentation. Extremely unprofessional behavior. Yelled at IT.

He was terrible and unprofessional. Never responded to emails and when he did he was rude about it. Only has a midterm and a final. On the final he barely graded it and gave no partial credit, I had entire questions just marked out when I got over half of it correct. It was clear he did not care and was being lazy with grading. Terrible professor.

(I took him in the summer term ii 2023 semester so he may be different regarding the regular school year) 

His class was easy since the first two tests were only 4 questions each. If you get a question wrong, as long as you provide him with your workings, he will give back the majority of the points. Overall, a great teacher that is very lenient.

Dr. Ryu had amazing lectures with lots of examples and could answer any related question, which really showed that he knew the material. One midterm and one final, with the final being very hard, and homework got better with either partial credit or multiple attempts. He would not go against the rubric often and to be fair did not offer much EC.
