What Students Say

The homework can be time consuming as usual with upper division math courses

MATH342 - 4.0 rating

Very test-heavy, I would not take this class again, can't sleep properly cuz of him, useless practice finals, didn't help at all with my preparation for the actual final, the midterms as well, his way of preparing his students for the midterms and finals is not professional at all

It's math. Practice is the best way to learn in this course. The quiz questions are taken straight from the textbook, so if you do them you should be fine. The concepts are best learned from practicing with the oq and cnq. His lectures are sometimes too fast but he's understandable and clear in concepts.

Amazing lectures

do NOT.. i repeat do NOT use his mock midterm exams as a means to look into/study course material you think will help/be on the actual midterms. Midterm comprised of not even 5% of the questions that were found in the mock exam and quizzes. exams are MUCH harder than any practice.

For the people saying his practice exams are so diff from actual exams he tells you to NOT to rely on the practice as they are diff and the actual will be harder. Do the CNQ and keep up with the material you will be okay. Quizzes most Fridays, only 2 questions, out of 8 marks. Good prof lectures can be a bit boring cuz of his monotonous tone.

practice practice practice!! i'm not great with math but it's the only way to learn. focus on cnq's for the quizzes, and don't even consider mock exams being remotely similar to the actual exam. hard class but imin's a nice guy

He's not a bad professor, but he isn't a good one either. Lectures are snooze fests and he goes at lightning speed so you're pretty much gonna have to review it while studying for the weekly quizzes. Also speaking of which studying is the name of the game, especially if you didn't do well in hs math; you're going to struggle. Do extra practice too

Good prof, always accessible outside of class in applied calculus workshop so it shows that he cares. Just get ready to spend lots of time outside of lecture to watch videos and practice concepts as lectures can be fast-pace and confusing at first. Also he teaches Calc III material in 157 so get ready (Multivariable Calculus)

Imin has slides and does not teach in class rather fills in blanks. His textbook questions are so hard that the ACW TAs cannot even solve them. He cannot control the class, and his exams are MUCH harder than the sample practice. It's like he wants you to do badly. Avoid at all costs. People giving him good reviews need to go to a mental hospital.

Very test-heavy, I would not take this class again, can't sleep properly cuz of him, useless practice finals, didn't help at all with my preparation for the actual final, the midterms as well, his way of preparing his students for the midterms and finals is not professional at all.

DO NOT TAKE THIS CLASS!! Lecture slides are useless fill-in-the-blanks. You're better off teaching yourself the topics or watching videos because his explanations are pointless. The workload is extremely heavy plus quizzes every Friday. One of the hardest classes and a huge amount of people who take this class FAIL and will take it like 2-3 times.

My goat 👑 If you're taking this class try to plan going to the Applied Calc Workshop (ACW) after math classes. The ACW is the literal method to do good on the weekly quizzes and midterms/final. TAs and Prof Chen were super helpful for questions in the ACW. I failed math last year but locked in and cooked thanks to Prof Imin Chen. 🙏

Decent Prof. Lectures get boring and on Friday when it's quiz day the low GPAs at the back talk over him but he seems to not have control of the class. Accessible outside of class at workshop for help. Midterm1 was fair, midterm2 challenging n not related to practice. Final exam was easier than expected, just put in the work and you'll pass w imin.

Utterly shocking. He didn't teach me a single thing. But the final was pretty easy so it wasn't horrible.

Exams are very different from the practice questions, so make sure you actually understand the concepts and how to apply them.

Not a very good lecturer -- does not explain concepts well and moves too quickly through lectures. However, the midterms were extremely fair and the final was quite easy. I would recommend him overall.
