Math Major
Official Requirements:
- The official requirements can be found on our Bulletin page.
- The department requirements are in addition to the University’s basic requirements for undergraduate degrees. The department expects majors to be familiar with this information.
- If you have questions, please contact the Student Services Specialist.
Departmental Requirements for the Math Major:
The Math major requires 64 units. Information on Honors in the Major can be found below.
Note: Math courses taken during Spring 2020 or during the 2020-21 academic year that ordinarily count toward the Math major will still be valid if taken S/NC (Spring 2020) or CR/NC (2020-21). These will not count against the limit of 6 CR/NC elective units that may be applied towards the major. Transfer credits for courses taken elsewhere during Spring 2020 or the 2020-21 academic year and judged equivalent to Stanford courses will be treated the same as those Stanford courses.
Core Math Courses (49 units)
- 49 units of Math Department courses all taken for a letter grade (at least 24 units must be taken from Stanford).
- The above letter grade policy does not apply for courses taken in Spring 2020 and the 2020-2021 academic year due to COVID-19. Please see the official requirements.
- If a student has 10 units of AP Calculus BC, and has completed either the Math 50 or Math 60CM/DM series, this leaves a remaining of 8 Math Department courses above Math 63CM/DM. Math 56 can be counted towards the 49 units.
- AP Calculus credit can be counted towards these 49 units.
- Stats 116, Phil 151, and Phil 152 are viewed as Math Department courses and can count towards the 49 units. No other courses outside the Math Department can count in this way. There are no exceptions to this for any reason.
- Math Q courses can be counted towards the 49 units.
- Math 51M and Math 193 cannot be counted towards the major or minor.
- If a course is cross-listed, in order for it to be used towards the 49 units, majors MUST enroll in the Math section.
Electives (15 units)
- 15 additional units of electives is required for the Math major.
- Math Department courses numbered Math 101 and above can be used as electives.
- In addition, there are approved out-of-department electives that can be used as electives. See the table in the next section to see these approved courses.
- Math 199 may only be counted towards electives, not towards the 49 units of core Math courses.
- At least 9 of these units must be taken for a letter grade (majors may take up to 6 units for CR/NC).
- The above letter grade policy does not apply for courses taken in Spring 2020 and the 2020-2021 academic year due to COVID-19. Please see the official requirements.
Petition for an Elective:
A course that uses a lot of numbers or basic algebra doesn’t necessary qualify as an elective for the Math major. There must be a certain level of Math that is used throughout the course (e.g., at least Math 21 or above) that demonstrated by course material such as exams, or a course website. For example: A Computer Science course that's primary focus is on coding, or a natural science course that is primarily focused on lab experiments does not qualify. See the table of pre-approved elective courses in the next section for a sense of this.
If you would like to petition for a class to count as an elective, please be prepared to provide either course material (such as exams or problem sets with solutions) or a course website which gives a clear indication about the level of Math used throughout the course. You can submit your petition using the link below.
Pre-Approved Electives
The table of courses below are automatically approved to be applied toward the 15 elective units of math-related courses allowed for the major.
- This list is not exclusive. The courses listed within the link at the red button above are what we commonly see majors take. If other courses are high enough in math content, they are likely to be approved.
- Primarily only undergraduate courses are included here, but many graduate courses may also be used.
- Please contact the Student Services Specialist well in advance of graduation (ideally by fall quarter of your senior year) if you have questions about the usability of courses not on this list.

Writing in the Major (WIM) Course
One WIM (Writing in the Major) course is a University requirement for the major and must be taken for a letter grade. The WIM course is part of the 49 core Math major units.
- The Math WIM courses to choose from are: Math 101, Math 109, Math 110, Math 120, and Math 171.
- Note: Math 101 must be taken 2015-16 or after to be a valid WIM course
