Applications are now available for Boston University’s PROMYS, a six-week (July 4-August 14) summer program — online this year — 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 $2500 and financial aid is available as necessary to ensure all who are selected may attend.  Applications are due March 15.
