He makes things that I already understood unclear

He's a really tough grader and is barely helpful in office hours. It feels like he intends to fail students on purpose. Don't be fooled by his friendliness, he's brutal.

Extremely tough professor. I noticed that this course also includes concepts from Math 128A so if you haven't taken that course or any upper division math course, then this class will be extremely difficult. The homework were extremely tough and he grades very harsh. He takes off points over the tiniest things. Take it with another professor.

Do not be fooled by his smiles. He is unwavering in his arbitrary beliefs, and will dock points for the littlest of things. He expects an exorbitant amount of effort yet is extremely apprehensive in awarding credit where it is due. I have warned you: avoid him at all costs.

This course is exceptionally challenging and taught at a rapid pace. Avoid as you can.

I did not gain much from his Summer Math 185 despite earning an A. Attendance at his lectures was VERY low, and a substantial portion of the course relied on prerecorded videos rather than in-person instruction.

ryan speaks the language of mathematics. most of the time, i have no idea what he is talking about. he speaks quite fast and writes just as fast. the lecture recordings are not made available to students, the writings on the chalkboard also do not line up with the posted notes. he skips through sections at will.

Smart man but bad professor. His exams are far more difficult than other profs teaching 54, he's only taught 54 once before afaik (Summer 2018), and the resources he gives for exam prep are lackluster. If he's your option vs literally any other 54 professor (even if the other one has 8AMs or smth) PLEASE take them over Hass, you wont regret it.

Hass is brilliant, but he struggles to carry that intelligence over into a lower division math class. I have quite literally studied for dozens of hours before midterms, only for the practice problems, homework, and textbook to simply not show up. His tests are the hardest I have EVER seen, and this is his second(?) time teaching the class ever.

Really bad, don't take

He was a bad lecturer, was not very inviting. Additionally, his exams felt quite different from the way he taught us the material. I found it very difficult to learn from him. Also, he assigned so much homework, which was so unnecessary. He also frequently made mistakes during the lecture and would correct himself a day or so later.

Exams were way too theoretical compared to other professors & not at all like practice or homework. Did not give any information about test format nor release accurate practice tests before exams. Unless you are really really into theoretical pure math, do not take this with him.

His lectures were so confusing, felt like he was just reviewing content as if we had already learned it. The home work questions were not helpful for the exams at all. He provides a very small set of practice questions for exams, and none of those questions are covered on the actual exam. Doesn't provide any previous exams to practice with. Avoid.

I mean pretty much echoing what the previous students have said. Professor Haas is obviously incredibly good at math, but not a great teacher. Lecture videos were gatekept until end of the year, and exams were not like review guides at all. Yes he's smart, no I would not take another course with him.

I actually had such high hopes for this professor and I have just been extremely disappointed. His practice exams are insanely useless, the hw doesn't actually help. Genuinely for the upcoming final it's like going in blind. The GSIs often show frustration because students seem very distressed over grades during discussion

You would think that since 80 percent of the grade is exams that he would prepare you well for them. His exams incredibly difficult and none of the problems on the singular practice test he gives you for each midterm comes up on the exam. I am terrified going into the final and just hoping the curve is good to pass the class.

the practices are nothing like the exams... hardest math prof ive ever taken and so pointless.

Tests worth 80% of grade but questions werent even related to the class. Ryans class is the worst class Ive ever taken at berkeley and I even like maths and theory

taught myself the entire curriculum because his lectures were confusing/waste of time and he posted no materials. don't know a single person who took this class and actually learned anything from him.

I never found lecture helpful, they were more theoretical than expected. I essentially had to self-teach myself the entire class. The homework and discussion worksheets barely helped me prepare for the midterms and final, and his practice exams barely mirrored the actual exam, making it difficult to do well. Don't recommend, avoid if possible.

I would rather have gotten up at 8am every day for sharma's class

Waste of time and tuition to take this class. What is tuition for if I am supposed to self-study?

I found this course challenging due to its heavy focus on theory, which made lectures hard for me to follow. The exam content didn't always match what I expected from lectures. Homework was heavy, but there were few practice exams. Since exams make up most of the grade, I had to self-study a lot.

The textbook definition of mediocre. He follows the textbook way too closely, introduces tons of theorems without offering any intuitive explanations, and provides practice exams that are far from related to the real exams. It's a struggle to keep up, and the lack of clarity makes learning harder than it should be.

His teaching is rough. Lectures are super fast and hard to follow, mostly theory stuff that doesn't help much. The homework is a lot but doesn't really prep you for the exams, which are way harder than anything we practiced. I basically had to teach myself the class. Wouldn't recommend at all!

Don't be fooled by the curve, so much of his lectures are hard to follow. Save yourself some time and read the textbook instead.

Lectures were so theoretical, explanations were confusing, and pace was really fast. Homework took a lot of time up and they weren't helpful either.

It was so hard to learn in this class, it felt like all of the learning I did was by myself because his lectures were all over the place

A lot of mistakes in the lectures and notes that needed follow ups and it made it hard to learn anything. The tests were real hard too

Lectures were practically pointless. He jumped between topics at will and had messy work on the chalkboard

Discussions were required and I mostly just read out of the textbook, which helped a lot more than lecture did

Take this class if you want to learn by yourself and go into every exam blind

He does not explain anything and it like an upper div class.

Class was hard, lectures were long, and discussion is mandatory

Such a hard class and had no support even though discussion was required. He waited until the last day of class to release all the lecture recordings so lecture was basically required too, even though it was never helpful at all.

Followed the textbook really closely, so really no difference between reading the textbook and going to lecture. Tests were the hardest I've ever seen, nothing like anything covered in the lectures or the textbook.

The class was ok until he rushed into the differential equations part of it, then I was lost and he said that it would be on the final but it wasn't even on it

I took this class in the summer and he barely rushed over things that were important for the exams and went off on weird tangents in lectures

This class was frustrating. Lectures were disorganized and often confusing, so it felt like we were teaching ourselves. Questions were brushed off and it was like they didn't matter to him.

Not helpful at all. Would not recommend to anyone trying to learn linear. Take Paulin's 1B and 56 if you wanna actually learn about diff eq and linear alg, the lectures are so much better and you'll get a lot more out of his class.

I found it to be more helpful to read the textbook for this class. The only helpful part was discussion and the GSIs were often frustrated by how students didn't understand anything from Ryan's lectures and his irrelevant worksheet questions. Same with his practice tests, which had questions that weren't related to anything in the class.

Genuinely the worst professor I've had. The class might be organized but it is so robotic, it's like trying to talk to a robot when you have questions. He teaches like he's on autopilot and even the things I've learned before are made confusing in his lectures. It's like I'm unlearning or something in this class.

Nothing relevant to 80% of the grade: exams. Lecture? Not tested. Discussion? Insane questions that were not tested. So how do you prepare to get an good grade in this class, other than ridiculous amounts of self-study? Office hours? Not much there either. Truly by luck (god bless my luck, can't say the same about the class though).

Math 1A is the only class you should take. Legit only used Paulin's page the entire semester.

Not much to say, just all-around bad lectures, discussions, exams

Very subjective in his grading and the rubrics are very vague. If you're good at guessing then you should probably take his class

I've learned linear algebra already but I wanted a refresher and WOW! I think my understanding actually REGRESSED. I started learning more when I STOPPED going to lectures. Do not take this class.
