Realistic Prerequisites

  • 18.100 is a hard prerequisite.
  • Experience with proofs and some set theory knowledge is helpful.

Subject Matter

  • The course material is very theoretical, broad, and useful in future topology courses.
  • “More theoretical, and helped me better understand parts of 100B I was confused on. Allowed me another way to look at analysis which I found particularly useful.”

Course Staff

  • The professor was kind but not a good lecturer.
  • Students did not have much interaction with the TAs.


  • Many students did not find the lectures helpful and studied from the textbook instead, which had similar content and was better organized.
  • Lectures were generally difficult to follow.

Problem Sets

  • Problem sets were doable, but sometimes tedious and challenging.
  • Problems were from the textbook and generally well-chosen.


  • Students felt prepared for the exams following the lectures.
  • Exams were fair and did not require much creativity.
