The best math professor ever. Lectures are interesting and he posted recordings for most topics from previous years. Grading on exams are super generous. Super helpful in office hours. Respond to emails very fast. Overall great class and great professor. By the way the TA Arthur is amazing too!

Great lecturer and he is good at explaining things in office hours too. Reasonable tests and homework, class work is fairly straightforward and easy in general, just go to extra hours and talk to him and the TA and the class will be even easier!

I retook the course with this professor after getting a D+ in my first attempt of math3B with a different professor and I wish I had him for math3b the first time. exams were fair in terms of difficulty and the professor was great at explaining most concepts and would show us multiple examples which i found helpful.

Amazing professor. I'm taking his Number System and Combinatorics this quarter. The workload is ~4 questions/week/course. One of the most memorable moments was when a HW problem in Combo was a trivial case of an open problem. I emailed him at midnight, said I proved a stronger result. He replied super fast with tons of books and related materials.

Five points might be the upper limit of rate my professor, but definitely not the upper limit of Karel.

he admits himself that he's not an expert on this class and isn't really good at explaining but makes up for it by giving out free homework scores. you only need a 60% on hw to get full credit, but can sometimes be a hassle. exams are pretty computation heavy. dont expect the exams to be a copy past of the practice, theyre not. anythings fair game
