This page is intended for anyone interested in taking math courses at Harvard, no matter your concentration!
If you took Math 18, 19 or 21 and are wondering what math to take next (or applied math, stats, computer science etc), please have a look at the handout "What classes to take after Math 18, 19 or 21?", it was created using collected thoughts and advice from students who've done this before you!
Here is also a video recording of an info session on math courses that happened April 22, 2016. I hope you find it useful!
You might also be interested in this flowchart of Math Department courses. (More flowcharts to come for students who took 23, 25 and 55.)
Students have also produced their own extensive advising pamphlet on math courses and the math concentration, please see this page of the Harvard Gender Inclusivity in Math (GIIM) website.
For one math concentation student's advice and perspective on taking math courses, learning how to study, and other tips and advice, watch this video interview with Anthony Clark '16.
Finally, you might get a lot out of this short 6-minute video of an interview with Elisenda Grigsby, Professor at Boston College and Harvard College alum. This video contains advice on choosing courses, finding one's own trajectory, learning proofs, graduate school, becoming a mathematician, the ego culture, etc.
