Syllabus wasn't completed until halfway through the quarter. Said attendance was mandatory but never set up a method to count attendance (never set up iClicker). Never answers emails, don't even try. Lectures are mostly useless, some good notes, but definitely sign up for CLAS, go to section, and learn concepts on the homework.

40% of the class got an A or higher. The average for the midterm was 90%. His lectures aren't bad at all if you read the textbook a bit beforehand. However, he does many of the similar examples over and over again, and like to jump to another concept in the middle of a question.

This professor is awesome. He is intelligent, respectful to the students, interesting, and accessible outside of the classroom. His homework doesn't take too long to finish, and office hours and sections are very helpful. Don't be frightened away by his grading scale. His test questions are very fair and he post detailed question types before exams

By far the easiest class I've taken at UCSB. The person disliking all his good comments is salty because they took an L in such a freebie class.

Professor Ye gives really fair tests. He even tells you exactly every question that will appear on tests word by word, and you'll see the same questions without any single change in wording on your exam papers. He goes over lots of proofs in class tho, which are kinda irrelevant, but you can just relax as he doesn't put those stuff on tests either.

he records lectures but its all just him doing proofs. he didn't get through half the linear algebra content so you're probably going to have to self study the course at one point in time (at least) his lectures are also really unorganized, he goes through the textbook theorems so u might as well just read the textbook

Easy homework. Fair tests. The professor just need to work on the ways he explain things.

Easy A

Skip the lectures. They were all about proofs and did not correlate with what you were learning. He's also hard to understand. The TAs were so much better at teaching. We only got through half of the linear algebra curriculum too. The final and midterm were easy though since he told us what each question on them were going to be.

He is so kind and patient with students. He is also earnest and helpful with every question that you have. The tests are very straightforward. If you follow the instructions he posted about the midterm and final, you can get really great grades on them.

His lectures were mostly proofs, but it would've been better to have more explanations since linear algebra is very conceptual. We only learned half the course material. I got through the course just fine by using other resources (youtube, CLAS, etc.). His exams weren't too bad and he told us the problem types beforehand and allowed a cheat sheet.

Know that his lectures are pointless and that you won't come out of them smarter. Best is to just read the textbook and self study. His tests are very straight forward as he literally tells you what will be on them. Everything else about him is very disorganized and I don't think any planning went into this class. TAs made this class much better.

Very easy class. He literally post the exact test questions, it's like handing out free A's. 50% weight for final and 25% for the midterm sound scary, but the TAs are very generous. Lectures can be difficult to follow along, but your section TA will clear up all the confusion.

You can basically skip lectures and learn everything from the sections and CLAS. Webwork takes around 20 minutes each week. He post the exact test questions (without numbers) before the exam, so you can just focus on those. Test questions are fair and you also get to bring an entire sheet of notes. By far the easiest professor.

TAs will teach each weeks concepts in 50 mins compared to the 3 hours of lecture you spend with Rick. Lectures are so pointless he's practically a meme. However, the class is not hard and he gives exact problems before the tests. You will just have to self study everything.

He is unfit to teach Math 4A, or any other lower div math class. Covered only half of the material, did not even mention eigenvalues/eigenvectors or diagonalization. His lectures consist of staring at the computer and proving every single concept in class.

I went into this class with low hopes due to the existing ratings, and he did not disappoint. I am dumbfounded as to how this professor is allowed to teach. The lectures were wildly unorganized, we covered approximately half the total material, and any real learning must be done through self study. Midterm and final were easy though. Avoid him.

If you teach yourself all the concepts he tests on the midterm and final you'll be fine. His lectures consist of only proofs. I eventually just stopped going to lecture all together and just relied on section and CLAS. Basically, his only job was to give us a final grade which he couldn't even do. Temporary grades Ye????

Very clear on what is going to be covered on exams. Gave us the almost exact wording of every question on the midterm + final. Midterm avg was 90/110 but he made it out of 100. Webworks were easy & extended due dates. Records lectures & gives helpful worksheets/textbook exercises + their solutions. If u dont pass 4a with him u are not trying at all

Don't take.

final is 50% of the grade; cannot teach you have to read the textbook or ur gonna fail. test was insanely hard but if you spend all your time in the textbook and understand all the concepts you'll be fine. only covered 1/3 of the curriculum so cant even say i learned linear algebra. avoid at all costs.

Get ready for a lot of self-teaching. His lectures primarily prove theorems and offer few examples. Dont rely on lectures and focus on self-teaching. He posts lectures on GS if you need. Kimberly Brehm, OCT, ThreeBluesOneBrown, and the textbook will save you. Midterm focused on concepts. He tells you what will be on exams (structure/concepts).

The following comment giving a positive review solely based on they have gained good grades is unethical and try to lure others into the abyss. Objectively speaking, in any circumstance, the professor is poor and incompetent, at least based on the performance of the 4A course he taught.

I HATE RICK YE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! AWFUL PROFESSOR!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
