(Fall 2023) He explained group theory decently well, although he went really fast; we finished the core material by Week 6, and spent the remaining time doing representation theory (grad level math to unprepared undergrads). Really funny guy though, and his tests were brute memorization so easy to game (not fun studying for though).

Best professor *ever*. Makes you think about how you should be thinking about the material and how you should be thinking about mathematics. Excellent in office hours.

Amazing professor. He lectures slowly and clearly and is very interactive. He always asks students for the next step of proof and guides students to complete the proof. Homework is a bit heavy and not easy, but it is manageable if you attend lectures. You can tell he has a lot of mathematical wisdom by the way he teaches. You will never walk alone.

Worst Professor I've ever had period. Doesn't care about students. Was able to find YouTube videos that explained concepts in a quarter of the time with infinitely more clarity than he had in lecture. Tests are extremely difficult. Grading scheme leaves no room for partial credit, you either get full credit or no credit.

Astounding in his immediate responses to say he can do nothing to help a student in need, or completely ignore the emails when it is not reasonable for him to say that. Does not care at all if his students learn anything, just shows up, lectures, and leaves. No communication, posts nothing online, he simply does not care. Actual lectures are fine.

If you take this class with Long, expect to learn nothing, feel super stressed, waste a lot of time, and get bad grades.

Absolutely excellent. The math is not easy, but it's upper division and his lectures were clear and well presented. Test were fair and based upon homework and classwork.

Teaches graduate level math with no curve. Tests are rote memorization with no thinking involved, just have to hope you got lucky and memorized the exact random proof that he talked about once. Is of little to no help in office hours, just acts like your question was nonsense and just moves on. Changed textbooks 3 times without telling class or TA

Run. Teaching differential topology in undergraduate math analysis class and the final exam is like a nightmare. It is literally the worst class I have ever taken, without exaggeration.

An amazing teacher. His teaching style made so much sense to me and the way he constructs things in class made the class entertaining. He really loves and understands his subject. Very glad I took this class.

5-min quizzes are worth 60% and final is worth 40%. Quizzes are really nerve-wracking. It's unclear what grade you have in the class until the final is over since there is no numerical grade for quizzes. If you do the weekly hw and attend lectures, you will do well. Not a bad prof, just didn't like the grading scheme

Dr. Long helped me understand linear algebra instead of just regurgitating stuff for tests. Attend class(zoom!), do homework, do practice problems you'll be fine. He has a system of five minute quizzes which makes it hard to cheat so dont count on chegg. He tests you on concepts so understand what you are doing and why. Great professor!

Terrific even though in the era of covid. Posts lecture notes (which are super-clear) and went at a steady pace. Answers all questions and very good in office hours. The 5-minute quiz isn't fun but I understand why he did it.

Professor Long is a really funny guy but I don't think he understood what being accommodating meant with regards to covid. With weekly 5 min quizzes worth 60% of our grade... I'd say kinda difficult especially online. He's fairly clear with his teaching but his grading scale was awful and unreasonable. I'm sure he'd be better in person

Prof. Long is mathematically brilliant, is a captivating lecturer, and tells amazing jokes. One highlight: "Life philosophy: It's never too late to beef up your obituary". However, he refuses to answer questions, obfuscates his office hour times, and limits Webwork attempts to three per question, disincentivizing learning. Smart man. Bad teacher.

Not an easy A. I got a 5 on the AP Calc AB exam and had to work for a B+. 1st half of the quarter is review of AB so I did really well but seriously struggled with new material because lecture is more confusing than helpful some times. Only section is mandatory and used to answer HW questions. Utilizing TAs and CLAS is really important!

I realy liked this guy. Gave old school lectures on a chalkboard. They went by quickly but the notes were great. Tests very fair, TAs helpful. Tells a joke most classes which helps.

Sensational professor. Makes tough material accessible and his lectures are funny and engaging. But he expects you to work.

Also, what bothered me the most was that he literally ended our hour and 15 minute lecture 15-20 minutes early every time by jokingly saying he's exhausted. This is one of the main reasons why we didn't cover some of the most important concepts such as improper integrals and Taylor series. When you add up the lost time, huge waste of tuition money.

Made students feel stupid after asking a question. Remember how teachers always said, "There's no such thing as a stupid question?", well he made it seem like the opposite, and that every student's question was stupid. Some of these students really wanted to learn. There were most times where he didn't know how to solve a problem. Not passionate.

I took Long for Math 3b and had a fine experience. The communication between him and his TAs was not great it seemed, as a lot of the things on the exams were not on my TA's review sheets. He told a joke at the midway point of every lecture, which gave something to look forward to. Only reason I got a B+ was because I failed the 2nd midterm lol.

terrible teacher. wouldnt wear a microphone and was so quiet. he was so sassy whenever asked a question and did problems way too hard and confusing on the board that we werent tested on

The concepts covered in Professor Long's class are conceptually difficult, but I think he did a great job of providing us with the materials to succeed. This class is not an easy A. You will have to spend time on the homework and put in a lot of effort to master concepts Long presents. His office hours help! I'd take him again.

The lecture is so boring and useless. The assignments and tests are really difficult than examples in class. Its really terrible.
