Applications are now available for Boston University’s PROMYS, a six-week (July 3-August 13) summer program for strongly motivated high-school students (ages 14-19) to explore in-depth the creative world of mathematics.  BU expects to run the program in-person this year. 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 $5,500 and financial aid is available as necessary to ensure all who are selected may attend.  Applications are due March 15. For more information, see the FAQs and then contact promys@bu.edu.
