About 80 students and 25 undergraduate counsellors spend six weeks on number theory and mathematical proof. It is separate from PROMYS Europe. The 2027 fee has not yet been announced. ## Context A six-week residential mathematics programme at Boston University for strongly motivated high-school students. ## Pathway - **Pathway context:** PROMYS (Boston) → PROMYS Europe ## Guidance ### Parent advice This is a six-week residential, not a short camp. The 2027 programme fee has not been announced. PROMYS offers substantial need-based financial aid, and the programme is free for domestic students whose families make under $80,000 a year. Students cannot apply to PROMYS and PROMYS Europe in the same summer. ### Student advice The application is a challenging problem set, not a timed contest. Give yourself weeks to work on it once the 2027 set is published. The deadline is late February 2027, but the exact day is still to be confirmed. Decisions are expected around the end of April 2027. ### Teacher advice Students need a letter of recommendation from a mathematics teacher, coach or mentor, plus a school transcript. Encourage students who enjoy exploring hard problems independently rather than racing through contest papers. ## How to prepare - Work through proof-style problems, not only multiple-choice papers - Leave several weeks for the application problem set once it is published - Practise explaining your own reasoning in writing ## FAQ ### When is PROMYS 2027? 27 June to 7 August 2027, at Boston University in Boston, Massachusetts. ### When is the application deadline?
