The lectures are very well organized. The instructor, a most prominent figure in the field of combinatorics, explains advanced mathematical notions without sacrificing rigor. I appreciated the option to retake quizzes as many times as one wants, even after passing them, to test one's understanding and assimilation of the concepts.
