A major chosen after arrival
Yale says every student begins undeclared and has until the end of sophomore year to choose from over 80 majors. The pages read describe no separate application to Applied Mathematics.

Yale Applied Mathematics: modelling skills with a field of application
Yale College admits students without a declared major, and Applied Mathematics is a flexible interdisciplinary major they can choose once enrolled. Yale's catalogue describes mathematical techniques used across natural science, social science and engineering, and a major that pairs them with a substantive field of application. This guide makes no claim of a separate application to the major.

What Yale says about Yale Applied Mathematics
Taken from the Yale College Programs of Study 2026–2027 entry for Applied Mathematics and Yale Undergraduate Admissions' Majors, Standardized Testing and International pages, read on 1 November 2026. The pages carry no entry-year label, so for a 2028-entry application every statement below is evidence for the previous cycle and may change; check Yale's pages for the 2028-entry details.
A flexible, interdisciplinary design
Yale says the major permits a great deal of flexibility, with core courses from computer science, mathematics, statistics and engineering.
A field of application
The catalogue says the major prepares students to use mathematical techniques in a substantive field of their choice.
Can be one of two majors
Yale permits a two-course overlap when Applied Mathematics is combined with another major.
The SAT or ACT is required
Yale's testing policy requires scores from either test; international applicants meet the same requirements.

Read on 1 November 2026 on the Yale College Programs of Study 2026–2027 entry for Applied Mathematics and Yale Undergraduate Admissions' Majors, Standardized Testing and International pages, which describes 2027 entry. The pages carry no entry-year label. Yale's department website, the course listings behind each course code, deadlines and financial aid were not read, and the admissions pages do not mention A-levels or the IB by name and are not stated.
The major
What the catalogue says the major is
Yale's catalogue says mathematical models are widely used in fields from physics to economics, and that the major provides a foundation in the core techniques and prepares students to use them in a substantive field of application. Multivariable calculus, linear algebra and computer programming are required early, and the B.A. programme needs eleven term courses beyond the prerequisites, including a senior project. Details of each programme are worked out with the director of undergraduate studies. This guide does not list individual courses.
Is it the right major?
Applied Mathematics beside other Yale quantitative routes
Yale describes these as separate majors, so the choice is made after admission. Avandy's comparison is general.
Applied Mathematics fits if
you want modelling skills tied to a field such as science, engineering or economics.
Statistics and Data Science fits if
your centre is data and inference. Avandy's Yale Statistics and Data Science guide covers it.
Computer Science and Mathematics fits if
you want theoretical computing alongside mathematics. Avandy's Yale Computer Science and Mathematics guide covers it.
Admission and testing
A Yale College application and the SAT or ACT
Yale requires first-year applicants to submit SAT or ACT scores and has no preference between them. International applicants complete the same application with the same requirements, and the admissions pages read do not mention A-levels or the IB by name. The major is chosen after admission, not applied for separately. This guide states no score.
A decision framework
Three questions before you commit
This is Avandy's own framework, not Yale's.
Which field of application would you pair with mathematics?
The major asks students to build a concentration in one.
Are multivariable calculus and linear algebra comfortable?
Both are required early in the major.
Can you plan the SAT or ACT with your A levels or IB?
Yale requires one of them for first-year applicants.
Planning for 2028 entry
Planning for 2028 entry: what carries over and what is awaiting publication
Yale's pages carry no entry-year label, so nothing on them is confirmed for 2028 entry. Use them to understand the structure of the application, then check Yale's own pages for the 2028-entry details.
The requirements and descriptions on the pages read on 1 November 2026, which carry no entry-year label
These are the best guide to what to prepare. Yale has not confirmed them for 2028 entry.
Deadlines, fees, financial aid and any department prerequisites not quoted here: not stated
This guide has not read them. Check Yale for the values that apply to your application year.
What to do now
Read the Applied Mathematics entry in Yale's Programs of Study and plan the SAT or ACT alongside your A levels or IB.
Support
Independent support with planning your own application
Avandy provides independent academic and admissions support. It is not affiliated with Yale College or any of its colleges or departments. Preparation sits within the Avandy Trinity Advisory Model: a Strategic Admissions Consultant, a PhD-level Academic Mentor and a Subject-specific Tutor, working to the actual requirements of each course. Support here is limited to understanding the requirements and planning the applicant's own work; Avandy does not write or edit essays, does not submit any materials and has no partnership with Yale College. No outcome is promised.
Questions
Questions applicants ask
Can I apply directly to Yale Applied Mathematics?
The pages read describe admission to Yale College. Students begin undeclared and choose a major by the end of sophomore year.
Can I combine Applied Mathematics with another major?
Yes. The catalogue says students may pursue it as one of two majors, with a two-course overlap permitted.
What mathematics is required?
The catalogue says multivariable calculus and linear algebra are required, with programming skills.
Do I need the SAT or ACT?
Yes. Yale's testing policy requires scores from either test.
Does Yale name A-levels or the IB on these pages?
No. The admissions pages read do not mention them by name.
Are these the rules for 2028 entry?
No. They are Yale's wording with no entry-year label. Check Yale's pages again when Yale publishes its 2028-entry requirements.
