SUMO provides student tutors for the Math 50s series classes who are available to answer questions about any of the three classes in the series. Additionally, we provide tutoring for MATH 104 and MATH 113 during designated hours. Our tutors can help you with homework questions or review the material covered in class.

No appointment is required to attend tutoring; just show up and our tutors will help you out. You don't even need to have questions beforehand; many students work on their 50s homework during tutoring, asking questions when they encounter difficulties.

This program is not aimed towards Math 50H students, but if you have questions feel free to drop by and discuss them with our tutors.

Please remember that although tutors are here to help, they are not substitutes for going to lecture and section. You should make every effort to go to class.


Starting the second week of each quarter, tutoring for the Math 50s series classes will occur Monday and Wednesday from 6:00 PM to 10:00 PM. We will also offer tutoring for Math 104 and Math 113 on Monday from 6:00 PM to 10:00 PM . Tutoring for the 2015 Autumn Quarter is currently in session and is held in the math corner, room 380-381T. Tutoring will occur on Memorial Day and continue through Dead Week.

If you are unclear as to whether there will be tutoring on a particular day or have any other questions, please e-mail Han Altae-Tran (hraut at stanford.edu).


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.

Becoming a Tutor

If you are interested in becoming a 50s 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 all three classes of the 50s series.

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 Han Altae-Tran (hraut at stanford.edu).
