# PROMYS at Boston University PROMYS (Program in Mathematics for Young Scientists) is a prestigious six-week summer program hosted by Boston University for high school students in grades 9–12. This immersive, in-person experience focuses on deep problem-based exploration in mathematics, with a particular emphasis on number theory. Students with a passion for STEM, especially mathematics, will find PROMYS to be a transformative opportunity to develop their skills, engage in mathematical research, and connect with like-minded peers and mentors. ## Program Structure PROMYS takes place over six weeks during the summer at Boston University’s campus in the United States. The program is conducted entirely in person, allowing students to fully engage with the curriculum and the community. The central focus is on number theory, and the program is designed around problem-solving and exploration. Students begin with foundational problems to build their understanding and gradually move toward advanced topics and mathematical research. The program includes lectures, collaborative problem sessions, and opportunities for students to tackle challenging, open-ended questions. Participants live on campus, fostering a vibrant community of learners and creating an environment ideal for intensive study and exploration. ## What Students Experience At PROMYS, students immerse themselves in deep mathematical thinking. The program emphasizes independent discovery, encouraging students to explore problems creatively and develop insights on their own or in collaboration with peers. Participants attend daily lectures that introduce new concepts and techniques, and they spend much of their time working on carefully designed problem sets that challenge them to think critically. In addition to the structured activities, students have access to mentorship from professional mathematicians, graduate students, and undergraduate counselors. This support system helps guide students through complex problems and inspires them to pursue advanced studies in mathematics. Beyond academics, participants form strong bonds with peers who share their passion for math, creating a lasting sense of community. ## Why It Matters for College Applications PROMYS is widely regarded as one of the most rigorous and prestigious mathematics programs for high school students. Participation in the program demonstrates a student’s commitment to STEM and their ability to tackle challenging intellectual work. Colleges value this type of extracurricular activity because it highlights a student’s passion for learning, their ability to work collaboratively, and their potential for success in advanced academic environments. Students who complete PROMYS often stand out in the college application process, particularly when applying to competitive STEM programs. ## Eligibility PROMYS is open to high school students currently in grades 9–12. Applicants should have a strong interest in mathematics and a desire to explore number theory in depth. While prior experience in number theory is not required, students should have demonstrated mathematical ability and enthusiasm for problem-solving. ## How to Participate To apply for PROMYS, students must complete the program’s application process, which typically involves a combination of essay responses, teacher recommendations, and a set of challenging mathematical problems. Applicants are encouraged to demonstrate their interest in mathematics, their problem-solving skills, and their motivation to participate in the program. The program fee is $5,500, though financial aid is available for qualifying students.
