리뷰
This is definitely one of the best math courses available. Prof. Loh explains the topics in a detailed way, and makes it fun.
This is an awesome course.
The video explanations are crystal clear and the challenges are fun. 5/5 would do again.
I think that this course was an excellent tool to “skim the surface” in the world of Combinatorics!
It tells every way to solve a problem and for problems, you get a turn to solve and get hints!

이 강좌에는 LIVE 및 자기 진도 맞춤형 버전이 있습니다. LIVE 형식을 강력 추천합니다. 학생들이 도전을 사랑하게 되도록 세심하게 설계되어 있기 때문입니다. 이런 방식은 지금껏 없었습니다. 모든 시간은 미국 동부 표준 시간대를 기준으로 하며, 11월 6일 일요일부터 미국 일광 절약 시간 조정에 따릅니다.
일정에 맞출 수 없거나 이미 특별히 동기가 강한 학생들을 위해, 자기 진도 맞춤형 버전에는 이 주제에 대한 Loh 교수의 가르침이 모두 포함되어 있습니다. 원하는 형식을 선택해 등록하세요.
