Most freshmen and sophomores interested in science, engineering, or finance take courses from the standard calculus and linear algebra sequence 103-104-201-202, which emphasizes concrete computations over more theoretical considerations. Note that 201 and 202 can be taken in either order.

Students who are not prepared to begin with 103 may take 100, a rigorous precalculus/prestatistics refresher offered only in the fall semester and intended for students whose highest math SAT score is below 650.

Prospective economics majors can minimally fulfill their mathematics prerequisites with (100)-103-175. Note that 175 covers selected topics from 201, with biology and economics applications in mind. Prospective math-track economics/finance majors will need the standard sequence 103-104-201-202 instead of 175.

More mathematically inclined students, especially prospective physics majors, may opt to replace 201-202 with 203-204, for greater emphasis on theory and more challenging computational problems.

Prospective mathematics majors must take at least one course introducing formal mathematical argument and rigorous proofs. The recommended freshman sequence for prospective majors is 215-217. Prospective majors who already have substantial experience with university-level proof-based analysis courses may consider the accelerated sequence 216-218 instead. Other possible sequences for prospective majors include 214-204-203 and 203-204-215, although the latter two are relatively rare. Note that 203 and 204 can be taken in either order.

Placement. Students with little or no background in calculus are placed in 103, or in 100 if their SAT mathematics scores indicate insufficient background in precalculus topics. To qualify for placement in 104 or 175, a student should score 5 on the AB Advanced Placement Examination or a 4 on the BC Advanced Placement Examination. To qualify for placement into 201 or 202, a student should have a score of 5 on the BC Examination. Students who possess in addition a particularly strong interest in mathematics as well as a SAT mathematics score of at least 750 may opt for 203 or 214 or 215 or 216 instead. 

Students must complete four core requirements:

  • one course in real analysis (e.g. 320 or 325 or 425 or 385)
  • one course in complex analysis (e.g. 330 or 335)
  • one course in algebra (e.g. 340 or 345)
  • one course in geometry or topology (e.g. 350 or 355 or 365 or 560)

It is recommended that students complete some of these core requirements by the end of the sophomore year. Completing these core courses early gives more options for junior and senior independent work.

Note: One course in discrete mathematics (e.g. 375, 377 or 378) can replace the geometry/topology core requirement, if desired.

In addition to the four core requirements, students must complete an additional four courses at the 300 level or higher(link is external), up to three of which may be cognate courses outside the mathematics department, with permission from the junior or senior advisers or departmental representative.

The departmental grade (the average grade of the eight departmental courses) together with grades and reports on independent work is the basis on which honors and prizes are awarded on graduation.

Students should refer to Course Offerings (link is external)to check which courses are offered in a given term. Programs of study in various fields of pure mathematics and applied mathematics are available. Appropriate plans of study may be arranged for students interested in numerical analysis, discrete mathematics, optimization, physics, the biological sciences, probability and statistics, finance, economics, or computer science. For students interested in these areas, a coherent program containing up to three courses in a cognate field may be approved.

Independent Work

All departmental students engage in independent work, supervised by a member of the department chosen in consultation with a departmental adviser. The independent work of the junior year generally consists of participating actively in a junior seminar in both the fall and the spring semesters. Alternatively, a student may opt to replace one junior seminar with supervised reading in a special subject and then writing a paper based on that reading. The independent work in the senior year centers on writing a senior thesis. A substantial percentage of our majors work with faculty in other departments on their senior project.

Optional Application Components

  • Arts Form, if applicable. If you've excelled in architecture, creative writing, dance, music, theater or visual arts, and would like us to consider your talent, consult Princeton's online Optional Arts Form. Early action applicants must submit digital arts materials by Nov. 7; regular decision applicants must submit digital arts materials by Jan. 6. You can only submit your online Optional Arts Form after we have received the Common Application, Coalition Application or Universal College Application. If you are unable to submit online, please use the paper Optional Arts Form. For a list of acceptable file formats and submission types, review our Optional Arts Form page. For more information on the optional arts supplement, please visit our FAQs page.
  • Interview. Depending on availability, once you have applied, you may be invited to interview with a member of one of our Princeton Alumni Schools Committees. If so, we encourage you to take advantage of this opportunity. Interviews take place after the Admission Office has received your application. Many Princeton Alumni Schools Committees have enough volunteers to offer every applicant an interview. As the interview is not a required element of the application, you will not be at a disadvantage if an interview is not available in your area. We do not offer on-campus interviews. Please visit our FAQs page for more information.

The full need of all admitted international students is met the same as it is for students from the United States. Your family’s ability to pay for your university education is not a factor in our admission decision. Students who qualify for financial aid will receive a grant, rather than a loan that has to be repaid, and a term-time job (8-9 hours per week) to meet their need as determined by the Financial Aid Office.

Our financial aid program is entirely based on need. Princeton does not offer academic or athletic merit scholarships. Financial aid awards cover the difference between Princeton’s costs and the amount your parents are expected to contribute to your education. The parental contribution is based on our evaluation of your financial aid application.
