Peer Math Tutoring


SUMO works with the Stanford math department to provide peer tutoring services for a number of introductory math classes, specifically MATH 19, 20, 21, 51, 52, 53, and 104. The peer tutors are available to answer any questions you have about the material and homework in these classes.

Peer tutoring hours are drop-in; just show up and our tutors will help you out. Feel free to come and work on your homework even if you don't have any specific questions. Many students work on their homework during tutoring, asking questions if they encounter difficulties.

Please note that this program is not aimed towards Math 60CM/DM students. For students in higher level math classes, the math department offers other resources.

Becoming a Tutor

If you are interested in becoming a peer math tutor, we hire new tutors at the start of Fall, Winter, and Spring Quarter of each academic year (if there are available positions). Tutors should be able to help students with either all three classes of the MATH 19/20/21 series and MATH 51, all three classes of the MATH 50s series, or MATH 104/113.

Tutoring position announcements are sent to the SUMO mailing list. If you do not want to subscribe to the SUMO mailing list but would like to receive tutoring announcements, or if you have any questions, please e-mail Nitya Mani (nityam at


Starting the second week of each quarter, tutoring for the Math 50s series classes will occur Monday-Thursday from 6:00 PM to 10:00 PM in room 380-381T. Tutoring will continue through Dead Week but exclude university holidays.

Tutoring will focus on Math 51, 52, 53, and 104 on Mondays and Wednesdays. Tutoring will focus on Math 19, 20, and 21 on Tuesdays and Thursdays.


One of our tutors, Joseph Victor, wrote a supplement to the Math 51 textbook and lectures. They can be found here.

Another one of our tutors, Arun Debray, took lecture notes for Math 53. They can be found here.
