Can't tell if the material itself was insanely hard or if he didn't explain it well... Lim was really nice and tried his hard to explain things in O.H. but it felt impossible to get. Midterm was easy, he said most ppl got an A there, final was crazy hard (even with curve). Weekly section quiz was easy, but lectures are unclear and very fast paced.

Professor Lim is a tough professor, but he is very accommodating if you have issues with homework or tests. His tests do not have any surprises and are straightforward. He is very knowledgable

Lectures were necessary but he posted all notes online which was very helpful. Homework is all on webwork which takes a while but isn't too challenging. Midterm and final weren't that hard but he barely curves. He has a thick accent but I love his enthusiasm and personality

Test are pure memorization and during lecture he will often be confused by his own notes and have to pause for several minutes to figure things out. The class material is hard but doable if you spend a lot of effort studying lectures and homework which I did not.

Excellent professor. The material is difficult for sure, but Prof. Lim really cares and tries his hardest to help you succeed. Tests are largely memorization-based, which is unfortunate, but the grading criteria is really generous in my opinion.

Math 117 is a hard course with abstract concepts. However Lim really did a great job to help His lectures are clear and he is also willing to clearify any point. Always reachable during office hour and is the most patient professor I have ever met. Trust me, he is the man who leads you to upper division math.

It's a hard course, but his tests are pretty easy because they are just repetitions of the homeworks and the lecture notes, which means you only need to memorize for preparing the test. He gives a good curve in the final grade calculation!

The class is abstract for sure, but Lim explains things in an understandable way and is always willing to explain your questions. If you work hard on homework and lecture notes, you can get an A without difficulty.(though he made the midterm time really short, he managed to curve up, so no worries!)

Avoid! Completely inexperienced, not many good things to look at. His teaching did come across to me at all, and his midterm was ridiculous-- the average was something like 35%!! Even if you need a class he's teaching I would highly recommend pushing for another quarter because there's a solid chance you will fail his class.

Took this class during winter 2021. I was gonna give him a one star because of how bad the midterm was. But he made the final much more bearable, giving less questions with double the time. He gave plenty of time to finish the homework (more than a week for each). His explanations weren't the best tho.

Literally hate this class. I should have just waited next year to take it because his lectures are hard to follow, the homework takes HOURS to finish, he doesn't know how to explain the math problems, and literally doesn't tell us any specifics about the midterm or final. The TA's don't even know what he's doing. SAVE YOURSELF THE PAIN.

as a person he's really sweet, esp in office hours. however, his lectures don't make that much sense. our midterm was 20 multi-part questions and our final was 22, which he changed from 30 after student concerns. our midterm avg was 65ish, so he curved it up to 82, and is not planning on curving final. tests very similar to hw (webwork style)
