# of Responses to Course 18 Underground Questions 7/23

Realistic Prerequisites

  • 18.01/18.02 is necessary
  • Mathematical maturity: some prior proof-writing experience is helpful. 18.100 suffices for proof-writing experience.
  • 18.06 isn’t necessary but makes the course easier.

Subject Matter

  • Theoretical: the course content was very theoretical. There wasn’t much emphasis on solving differential equations.

Course Staff

  • Caring and approchable: the staff were always willing to put in the time to explain things.


  • Mixed opinions about pace: some students found lectures fast, and some found lectures slow.
  • Lectures were theoretical whereas recitations were about applying things learned in lecture.

Problem Sets

  • Interesting: Students found the problems sets interesting!
  • The problem sets were structured with subparts and hints per problem, and the problems were greatly related to lecture content.


  • Practice tests were made avaliable and were useful.
  • Challenging: the exams were challenging, but grading was lenient.


  • There was no textbook for the course.
  • The instructor published lecture notes for each lecture.


  • It was not clear how other students were doing.
  • Students either found grading fair or very lenient.

Advice to Future Students

  • If you just want an overview of differential equations then take 18.032. If you are interested in the theory then this class is great.
  • Some prior experience with proofs and/or analysis is recomended.
