MIT PRIMES vs SUMaC: Which Program Is Right for You?
PRIMES is a school-year research program where you produce an actual paper with MIT mentorship; SUMaC is a Stanford summer course sequence in advanced pure math. Research output versus coursework depth is the real choice here.
Below is a side-by-side comparison of MIT PRIMES Research Program and Stanford University Mathematics Camp (SUMaC). A blank row is a fact we do not hold — not a zero, and not a no.

MIT PRIMES vs SUMaC: the short answer
PRIMES is a year of research; SUMaC is a summer of courses. At PRIMES you spend a year on an unsolved problem in mathematics or bioinformatics with a mentor — usually an MIT graduate student or postdoc — at least 10 hours a week, present at a conference in October, and write a paper that may go to competitions or journals. It is free. SUMaC is three weeks online or four weeks residential at Stanford, studying abstract algebra and number theory or algebraic topology through lectures, problem sets and a final project, with no credit or grades; tuition is $3,750 online or $8,950 residential, with need-based aid and a $65 application fee. Both are for 10th and 11th graders and both admit on a proof-based problem set you do at home. The calendars are the useful part: PRIMES's 2027 applications are due November 2, 2026, while SUMaC's last deadline was February 2, 2026. PRIMES even names SUMaC among the summer programs that strengthen an application.
Program details
These are the current details stored for each program. A blank cell means the catalog does not hold that detail.
| MIT PRIMES | SUMaC | |
|---|---|---|
| Cost to attend | Free: PRIMES is a free program. | Tuition of $3,750 online (course materials up to $100 extra) or $8,950 residential. |
| Fees and aid | Not stated. The PRIMES apply page names no application fee, and the program itself is free. | Need-based aid, open to all applicants; applying for it does not affect your admission decision. |
| Who can apply | Juniors and sophomores, including home schooled, living in the United States; local students meet mentors in person, others by video. | Grades 10 and 11 when you apply, at least 15 during the program; students 18 or older can do the online program only. |
| What you work on | Unsolved problems in mathematics and bioinformatics with academic mentors, usually MIT graduate students or postdocs; no new computer science admissions. | Abstract algebra and number theory, or algebraic topology. |
| Length and time | A calendar year; at least 10 hours a week, including a 1.5-hour weekly meeting with your mentor. | Three weeks online or four weeks residential in 2026: online June 15 – July 3 or July 6 – July 24, residential June 21 – July 17. |
| Places | A small number: PRIMES expects a very advanced background. | 40 residential and 64 online participants. |
| What the work produces | A final paper posted on the PRIMES website, which may go to national competitions or research journals. | No credit or grades: SUMaC courses are for pure mathematical enrichment. |
| The entrance problems | The PRIMES 2027 problem set; PRIMES encourages you to apply if you solve at least 70% of it. | An admission exam of challenging proof-based problems, worked at home before the deadline. |
| Deadline, most recent published cycle | November 2, 2026 at 11:59 pm EST; recommendation letters by November 6, 2026. | Monday, February 2, 2026 at 11:59 pm Pacific; notification in mid-April 2026. |
Inside MIT PRIMES
A year, in four phases. From January to Pi Day you read advanced material your mentor recommends and write a short reading report; PRIMES then invites the students with the strongest motivation and progress into active research until June 15. The summer is independent work in touch with your mentor, and the fall is for writing up: you present at the PRIMES conference in mid-October and finish a paper by the new year. At least 10 hours a week, fitted around school.
Inside SUMaC
A few intense weeks: daily lectures and problem-solving sessions, guest lectures, and a final research project presented at the end, with a college-level load of problem sets outside class. Online sessions meet Monday to Friday for three hours a day; the residential session lives on Stanford's campus with weekend trips. Nothing is graded and there is no credit — the program calls it pure mathematical enrichment.
Choose MIT PRIMES if…
- You want to do research, and to write it up as a paper. PRIMES is a year on an unsolved problem with a mentor, ending in a paper that may go to competitions or journals.
- You are applying this fall. PRIMES's 2027 applications are due November 2, 2026, with decisions by early January.
Choose SUMaC if…
- You want a concentrated summer of advanced coursework. SUMaC is three or four weeks of algebra, number theory or topology in lectures and problem sets.
- You want a residential summer on a campus. SUMaC's residential session is four weeks at Stanford; PRIMES has no residential part.
Applying next cycle: what to do now
| MIT PRIMES | SUMaC | |
|---|---|---|
| Decisions released | By early January 2027, to all applicants at the same time. | Mid-April, for the 2026 cycle. |
Applying to MIT PRIMES
- A personal statement of up to 2 pages about your most memorable math experiences.
- For the problem set you may use calculators, computers, AI models, books and the Internet, citing what you consulted — but not other people's help.
- Short-listed applicants have an online interview about their solutions and reading.
Applying to SUMaC
- A $65 application fee, with waivers if you qualify.
- Expected background: reading and writing proofs, and strong high school geometry and algebra.
What this comparison cannot tell you
- PRIMES's program page still describes the program as for students in Greater Boston, while its apply page takes students anywhere in the U.S.; ask PRIMES if the difference matters for you.
- Neither publishes an acceptance rate; SUMaC gives seats, PRIMES says only that a small number is admitted.
- SUMaC's 2027 dates, prices and deadline were not published when we read the site; the figures above are 2026's.
