Ratings for Ribet, K A
Based on 33 ratings for this instructor.
Comment: Enthusiastic and overall nice to everyone. Very helpful during office hours. Likes to host breakfasts and lunches with students, which is pretty interesting, but fun if you attend. Very friendly and will become your best friend if you want him to be. Very knowledgeable, that being said, exams are difficult, but if you go to office hours and pay attention in lecture, you should know what to expect. Personally found homework and exams difficult, but if you are going to take Math 55, Ribet is the man!

Comment: Professor Ribet is awesome and very approachable. His homework assignments are fair and the average response time to piazza was 33 minutes! His lectures are organized and the pace was fine. The only problem with 55 is that there are so many material in it that it is impossible to cover all of them and make every one of the 293 people class understand. That said, if you would like to discuss deeper questions such as the generating function theories and further applications, GSIs are a great resource. Professor Ribet also personalizes with students by organizing social events such as breakfasts and lunches.

Comment: Very friendly professor! Encourages students to ask questions during lectures. Homework is alright, covers only the concepts he went over in lecture. He's helpful during office hours. Exams are not hard, but the grading is very harsh, so make sure to write down everything to get full credit.

Comment: Ribet is probably the best math professor I've ever had. Not only he is a great lecturer and super knowledgable, he is also very down to earth. He consistently hosts lunches with students, and is willing to chat about just about anything!

Comment: Semi tough exams, funny guy. Will greet students when they come in late. A bit slow: we didn't get to cover the more interesting parts of linear algebra. Also likes to have a lot of lunches. Sometimes might be more enthusiastic about lunches than lectures.

Comment: Assignments: There are usually around 10 homework problems due each week. I found that I needed to spend at least 5 hours to do each homework. While the time I spent on homework was ridiculous, I feel it was kind of necessary in learning how to handle different types of proofs. Enthusiasm: Ribet will go out of his way to try to help you, if you seek the help. He is very active on Piazza (where I got many of my questions answered). He also has around 3 hours of office hours each week, where you can ask questions. As some other people mentioned, he also frequently hosts breakfasts and lunches where students can chat with him. I thought that was kind of cool. Helpfulness: Most of the material Ribet covered in lectures came directly out of Axler's book. Thus my primary source of consultation was the book. Ribet's posts on piazza were generally pretty useful. Exams: really difficult exams. The average for midterm 2 and the final were less than 50%. But the scores don't really matter, because grades are determined by your relative performance. Final note: try to have George Melvin as your GSI. He's awesome!

Comment: Ribet is the bomb. His lectures are crystal clear and fresh, and I actually looked forward to them because he was extremely animated and perceptive to his student's needs. Catch his Math 55 class in the spring if you can! It'll be great, guaranteed. :)

Comment: This was my first math upper div class at Berkeley. Homework was pretty fair, but you probably need to spend more than 5 hours each week. One thing that I did not like about the class was that there is no solution to the homework problems, so I always had to go to office hours for help. But this is understandable because you learn how to prove problems by trying hard and thinking about the problem for a long time. I also enjoyed Ribet's lecture style. If you pay attention to the lecture, the material he covers will be really clear. He also spends few minutes in the lecture to take students' questions in the middle of the lecture to clarify things. Whenever students ask questions on piazza, either professor or other students answered everything. Exam is fair if you do your homework correctly. Overall, the professor is very enthusiastic and helpful. Highly recommend this class!

Comment: Professor Ribet is undoubtedly one of the best instructors in the math department at Berkeley. However, I was not content with the way he handled some matters within this course. My biggest complaint is that he did not bother to distribute solutions for homework problems except for a few, based on his reasoning that online solutions would dilute the nature of problem solving for future students who will be taking this course. I totally understand where he is coming from but for students who never took an intensive proof-based course like this one-I feel like we could have benefited a lot by looking at the model solution. And there is always a way to watermark the solution to prevent students from leaking it online. Maybe, he might not have been aware of it since no one bothered to tell him about it. Nonetheless, I still got the impression that he did not really care for students who struggled with the course overall.
