This was the worst class I have taken at UCSB so far. The class was moved online in the first week of the quarter, the lecture content made no sense and the tests were extremely hard. The professor did not show up to any of the tests, including the final and made the final online in person, meaning half of the class cheated and he allowed it.

If you cant avoid him, PLEASE calculate your final grade based off the grading scale he provides and your exam, hw, and attendance scores. He input my grade as a C- when it was meant to be a C+ and it took him 6 months to correct the mistake. If this happens to you, reach out to the math dept. advisors and chair. He is very noncommunicative.

Worst professor in the UC sytem.

Professor Rick Ye was horrible. He's my 13th reason, can never understand anything in lecture and his lecture notes looked like some kind or foreign alien language. PLEASE avoid this professor at all cost like the black plague!!!

I rebuke this professor man!

Literally so disorganized and no clear syllabus. While math is usually a strong area for me, I would sit in his lectures and not understand a single thing. DO NOT TAKE THIS CLASS unless you know how to learn on ur own

To be honest I hated the guy until the final. Lectures primarily consisted of him waffling and you were better off reading the textbook. They were funny though. I got a D- on the midterm (which he curved to a C-). Then he gave an extremely easy final worth 50% of the course grade and I ended up with an A after the final curve. Peak cinema. 10/10

Horribly disorganized, bad handwriting, weird tangents, constantly corrects himself so you have to rewrite notes, and switches between going too slow and too fast. His phone went off 20 times during the final exam and he did not silence it. If you are forced to take a class with him, grading is reasonable and you do get a cheat sheet on exams.

Horrible at teaching, the tests did not reflect what he taught in class.

zero structure in lecture or section. almost no communication with students or TAs. 20+ questions of hw each week that are nothing like the exam. no information on dates/how many midterms until 1 week before. no study materials. luckily, TAs are very nice and give a lot of partial credit, which is the only reason this class was passable.

He knows a lot about math but just really is impossible to learn from. He has the sloppiest handwriting I have ever seen from a teacher or professor. I learned everything from CLAS. With that said the tests were grade rather generously so it isn't too difficult to do well if you spend time outside of lecture learning.

Rick Ye makes sure you have no idea what's going on in this class. I could not understand him or read his handwriting, not that it would've helped since his lectures are all over the place. No practice tests were provided for midterm/final. HIGHLY recommend to wait a quarter and take it with another professor. TAs very unhelpful and final is 53%...

run. keep running.

The professor may be good at research, but his teaching is VERY POOR. Lectures are hard to follow, and the notes are unclear. It feels like there's little coordination with the TAs. Overall, it's very difficult to learn in this class due to the way the material is presented.

horrible, please never take.

Can barely read what he is writing, and doesn't teach in a manner that someone who has no clue what is going on could understand. Changes due dates all the time so nothing is really ever set in stone, you get only a weeks notice for the midterm, and the syllabus is never set in stone. Overall a terrible professor, don't take him.

awful. iIlegible writing. Will not answer your emails. Does not tell you when exams will be until 1 to 2 weeks prior. No syllabus more like a notes page that gets edited frequently. Does not tell you the weight of exams for your grade instead gives you a range and decides at the end. Do not take this professor.

The worst professor I have ever had. His lectures are a mess, writing is illegible, he struggles significantly with technology, and his tests are extremely hard and unfair. The TA's are the only reason this class is passable. Avoid him as a professor if you can.

lectures make no sense, severe lack of good example problems that would be similar to ones on midterm/final. the Class is doable if you're good at learning math solely on your own.

Just lazy and nobody knows whats going on in the class not even the TA's

Professor Ye does not know how to teach at all. The midterm was nothing like homework or lecture notes. Reading the book does not help either, and the whole class percentage is basically midterm and final. Homework every week, min 15 questions and do not serve for NOTHING. i wish I had dropped before the deadline with the W.

I have no idea what is going on, I cant read his hieroglyphics.

Does NOT explain anything, talks to himself in lecture, and hopes you figure it out.

This is literally the worst teacher/professor I have ever had, in any subject ever, across all my 14 years of schooling. Absolutely atrocious. Do not take his class if there are any other options available. grading was 53% final, 20% midterm, 23% HW & 4% attendance. Going to lecture doesn't help since his handwriting and accent are comically awful
