Declaring as a Math Major

Registrar's Information About Declaring a Major (Spring 2025)

A.B. students preparing to enter their junior year must officially declare a concentration prior to fall semester course selection. The 2025 concentration declaration period is March 27 — April 14.

The department will hold a Sophomore Open House for prospective majors on March 19 at 3:00 pm in the Fine Hall Common Room, 317. You can also find information about the major from the 2021 Virtual Open House at this link: Virtual Sophomore Open House.

Steps to follow to become a Math major:

1. Indicate your intended concentration (MATH!) on TigerHub between March 27 — April 14.
2. Complete the Departmental Academic Planning Form (DAPF), and submit it in TigerHub. It will take one business day from your concentration declaration for the DAPF to become available to you.
3. Make an appointment with the Mathematics Department Junior Advisor to discuss your plans. E-mail Dr. Mark McConnell (markwm@princeton.edu) to set up this appointment. Attach a pdf of your course history printout to that e-mail, so that he can review it prior to your discussion. (Go to TigerHub>Student Center>My Academics>View My Course History.) This is a very good opportunity to discuss the courses you plan to take in your junior year and to begin planning for your senior independent work.
4. Once you have had your meeting with Dr. McConnell, he will be able to approve your DAPF, and thus your standing as a math major.
5. You must declare your concentration and have it approved before you are allowed to select fall term courses for your junior year. Since your day for course signup is April 17, and there is some delay between the beginning of the process and ultimate department approval, we suggest that you declare your concentration earlier in the March 27 — April 14 period, rather than later.
