Applications are now available for Boston University’s PROMYS, a six-week (July 2-August 12) residential summer program for strongly motivated high-school students (ages 14-19) to explore in-depth the creative world of mathematics. About 80 students are selected from a nationwide/worldwide pool based on online applications consisting of solutions to challenging problem sets, school transcripts, teacher recommendations, and short essays explaining their interest in the program. The cost is on a sliding scale by family income, and full or partial need-based financial aid is available as necessary to ensure all who are selected may attend.  Applications are due March 5. For more information, see the FAQs and then contact promys@bu.edu.
