Often, it is hard to get some of the formulae he used, maybe he thought those things were 'obvious'. The final is extremely difficult and extremely tough graded. I should have drop this course after midterm.",

I strongly recommend this course to students who aim to pursue a graduate degree in pure math. Others, like me, may respect it, but chose to drop it.",

Homework and exams are mostly reasonable, but sometimes it randomly gets extremely hard (such as on the Midterm and last HW). I appreciate his desire to make Topology accessible, but covering the same thing in 3 layers of abstraction is unnecessary.",
