He's an excellent lecturer. free style, but at the same time organized. tests have a few problems, but they're not easy. grading for this particular class was easy, but that's usually the case.

Awesome lecturer. Puts in WAY more time than most professors. Always willing to help and encourages students to come to office hours all the time. And, besides, he proved Fermat's Last Theorem is equivalent to Taniyama-Shimura!! What more could you want?!

You should take his class if you really like Math.

He is one of the top mathematicians around yet still managed to be a very nice guy.

i didn't get the grade i wanted in this class but that was due to lack of study time and had nothing to do with ribet's ability to teach. this guy is down to earth and super-smart and interesting. most math snobs are so condescending but ribet is smarter t

The best professor at berkeley!!! he is so kind and always willing to help.

one of the most devoted professors i have ever had. he really cares about the students and never seemed too busy for us. i really appreciated that even though i had some trouble in the course.

He is the best professor!!!

highly recommended to anyone that loves math or is very good at it. for others, he can be hard to keep up with. exams seem very fair... they seem based on his realistic view of the class' understanding of the material. he is extremely devoted to the students, and always has time (go to his website, you'll see all the student lunches he's been to).

Professor Ribet is a great teacher. He knows the material and his lectures emphasize some of the finer points about the subject. Sometimes they can be a little over your head but you'll be seeing what Math 54 really has to offer. The exams and grading system are very fair and it is very clear what you're expected to know for them.

professor ribet was a great professor...dont listen to any of the ocomments that siad his lectures were not clear. In order to experience the math department in berkeley, you have to take professor ribet. HE IS THE BEST!!!

do the homework and you'll get an A. the material is awkward, but ribet tries very hard.

As has been stated before, he tries very hard. He makes a genuine effort both to help stuednts learn and to get to know them outside of class. Despite this, however, his lectures can be confusing. He's a very fair professor, however, and I'd recommend him.

great professor. cares a lot about students. go to his office hours

He is a nice guy, but his lectures are a little unclear. His office hours are great though. He is really helpful and takes an effort to learn the names of every person in the class even though this was a class of 260. Overall, a pretty good professor if you stay on top of the material.

He's one of the best professors I've ever had. Excellent lecturing style -- clear, precise, interesting, and well organized. He obviously cares a lot about his teaching and is very accessible and helpful.

He's friendly and brilliant, which is a rare combination sometimes. As another reviewer said, "freestyle lecturer" is the best description of his style. He covers a lot of interesting material, but his chatty style made it difficult to catch what's important. The only predictable thing about his tests is how brutal they were (especially the final).

Ribet is an extremely smart guy. He's very friendly too. He gets to know everybody. Man, I dun noe how many hours this guy sleeps every day but i emailed him a couple times at 4-5 am n got his response in like 3 mins!!! His midterms kinda hard though, but final is very do-able! Make sure u can make his office hours!

Ribet is really affable and knowledgeable. Lecture style can make the class tough to follow, but you definitely learn a ton if you stay on top of the material. Tests were brutal, but if you work hard, you will do well.

Prof Ribet seems to be more concerned with being everyone's favorite person/teacher rather than teaching a good course. The homework frequently required doing research in the library or online as the material wasn't covered in lecture nor in the book. The midterms often had questions/material that was never seen before. Not my favorite teacher.

His lectures can be somewhat tedious, but Prof. Ribet is still a great teacher. He does his best to reach out to students despite the enormous class size, and he answers any and all questions directed to him on Google Groups or via e-mail as concisely as possible. He's also very easy to relate to or converse with, despite his elevated status.

Lectures were clear and had lots of examples. Still, boring at times. I definitely didn't get all the theoretical connections between things just from lecture. I struggled with them at home and in section. Tests were fair. Diff. eq part of class was not as well taught, textbook much worse. Make sure to ask GSI for help on those assignments.

Lectures are very boring. Going to lecture feels pointless. I learned everything from my GSI. Tests are OK. He's a fair grader. You can tell that he is genuinely interested in making his students succeed. "Turtle Turtle"

Great professor overall. Lectures can be a bit boring because his voice sounds so dreamy (not the good kind of dreamy). You learn most from homework and practicing problems. Still, Ribet is probably one of the best in the math department.

Very easy to communicate with because he made himself accessible through lunches, office hours, the Google Group, Facebook, and emails. Tests were fair; there was a good spread of problems, and he gives you enough time to do it. Keep up with homework and you'll be fine. Lectures were moderately useful; they served to introduce me to the concepts.

Really, really interesting and helpful teacher. Likes to have lunch with his students once in a while, and is very good at explaining concepts in office hours. Recommended.

A must-take professor! In 115, Prof. Ribet exposed us to so many interesting topics in an understandable way that sticks easily with memory. Lectures were enlightening and I wish I had gone more to office hours! The class lunches were a nice touch too..it shows well how the professor really cares about his students!

I took Math 55 with Dr. Ribet last semester, and it was one of the most enjoyable experiences. He truly does care about his students. Exams are a bit tricky but fair. Lectures are extremely clear. He mostly assigns evens in the homework, but this becomes rewarding as you don't rely on solutions to much. He is a must-take professor!

Professor Ribet for Math 10B is a good lecturer, and teaches the course in his own style. His lecture style is easy to understand if you consistently follow along, and he always pauses to ask for questions. Always organizes breakfast and lunches to get to know students personally. If he tells you the final exam is going to be hard-IT WILL BE HARD.

As a person, Professor Ribet is a really great guy who continuously tries to get to know his students better. However his lectures tended to be so convoluted and confusing. He really likes teaching about proofs / concepts that aren't even relevant to the exams. Learned mostly from discussions.

People need to distinguish between the course and the instructor. Ribet does extremely well for this subject. Math 10 is rapid, with complex concepts tied together in such a short time. The fault is not in his instruction, but within the course curriculum. Ribet is absolutely AMAZING. Clear, thorough, supportive and encouraging. would recommend :)

Lectures are pretty confusing at times and I found myself trying to catch up and learned things in discussion. I didn't have the best GSI so I didn't get much help. I basically learned everything from my friends and on my own. But he's genuinely a great person and very helpful at office hours. Overall, good person, not so great lecturer.

A VERY ACCOMPLISHED MATHEMATICIAN - WORLD RENOWNED

Professor Ribet is awesome, world-renowned, and loves to hold brunches/get to know students. His lectures can be confusing but if you have decent background in Calc BC/Calc3, you should be fine (I didn't often go to lecture). His class is curved and he's very generous with grading- I bombed MT 2 but did well on the final. Try to get a good GSI too!

Ribet is actually not that bad of a professor. It is said that his exams are very difficult, but I didn't find them to be too bad. Certainly, I think they are fair (be sure to explain everything!). Lectures are also fine. I do recommend going to them even though they aren't mandatory. I also recommend reading the textbook carefully.

Ribet is a mathematical god who teaches math the way it should be taught. It isn't necessarily the most straightforward, but it's enlightening to see his approach. He ties concepts back to other areas of math, and focuses on the motivations of those concepts. He's extremely active on Piazza, and actively fosters a culture of collaborative learning.

Gives clear lectures and enhances understanding by connecting the material to other classes or knowledge the students may have. Really cares about teaching and connecting with the students. Makes himself available outside of class and wants to get to know you as a student. Provides materials such as his own solutions and lecture notes.

He tries hard to remember every one of his students' names, and he sets up faulty brunches with students to have some one-on-one time to talk with us. Incredibly approachable, he wants us to succeed, he BELIEVES we will succeed, and he's a master of his art and incredibly renowned in his field. He's a great person and a brilliant professor.

He is the most caring professor I've ever met. He is super reachable during office hour and organized "Happy Hour" during quarantine time. He gave a clear lecture and exams are fair. But in general, Math 110 is a hard course, especially when you took it as the first Math upper course.

Loved his class. He's knowledgeable, inspiring, and hilarious all at once; his happy & office hours are fantastic and he's an amazing person and mathematician. I swear by his lectures (though I do have a pure math background). If you love math, take his classes!!!

Great guy, super accessible outside of class and active on platforms like Ed and Discord. I found his lectures very interesting and useful, and test questions were often taken directly from lectures, homework, and past exams. The course policies felt very fair and there were more than adequate resources to do well in the class. Would recommend!

Prof. Ribet is a very accomplished professor in his field so it was an honor to take a course by him. Midterms were hard but not impossible. Final was pretty easy. He cares about students and organizes lunches. Kind person. Only thing is I wish he gave the lecture on the chalkboard instead of LaTeX slideshow.

His handwriting is indecipherable (at least on the iPad), but he's really caring toward his students.

Loved the class... I would deeply recommend attending his office hours- He is the first professor at Berkeley who I would actually pay money for to listen talk. I hope he writes an autobiography one day.

His lectures are amazing and he is very accessible outside of class. His personality takes a little getting used to but I feel that he is a great teacher.

Bros goated

This guy is really the best. He is insanely intelligent and so the class may be hard to follow at times, but he will make sure everyone in the class who shows up and tries gets a good grade. I learned so much about math from him and he was so approachable unlike some of the "geniuses" here

This class is difficult— you won't succeed without actively engaging. Admittedly, Ribet's lectures can be hard to follow, but he makes himself accessible via email, discord, ed, office hours, and lunches. He will explain the material to you repeatedly if you seek him out. He's eccentric but hilarious, and has certainly earned his accolades.

Kenny's lectures follow the textbook closely, so you'll want to stay on top of that. If you're looking for a rigorous class and don't mind the workload, you'll learn a lot from him. Granted, this semester lecture/midterms were at 8AM so that could have affected how difficult it was for me. Anyways, lunch with him was goated.

Despite the class being at 8 am, Ribet's lectures were great and concise (my brain was just too tired lol). He was very accessible outside of class, always setting up lunches. Grading was definitely on the harsher end (more of a GSI thing) and there were some grading/binning issues. If you commit, you'll end up taking away a lot from this class.
