Welcome to ONEXYS!

Led by Dr. John Hall, Senior Lecturer in Mathematics, Online Experiences for Yale Scholars (ONEXYS) provides a cohort of incoming Yale students with the opportunity to prepare for the rigors of quantitative study at Yale before arriving on campus in the fall. ONEXYS participants receive access to a wealth of online content, including videos, real-time discussions with other ONEXYS students, advice and mentoring from the current Yale students who serve as ONEXYS coaches, and a variety of problem sets, quizzes and other assessments to help them enhance their transition to Yale in the fall. Many of the quantitative concepts and skills covered in ONEXYS are drawn directly from Yale’s introductory math courses and placement exams, and are utilized across disciplines in Yale’s curriculum—ranging from economics to chemistry to political science.

An Introduction by Professor Jim Rolf (ONEXYS founding director, 2014-2018):


As incoming Yale students, you’re busy and engaged year-round; ONEXYS allows its students to obtain an early edge in preparing for Yale without leaving their homes or giving up valuable summer jobs, research opportunities, athletic competitions, and other pursuits. It is an experimental, cutting-edge program designed for experimental, cutting-edge scholars, and will accelerate your academic transition to Yale and provide access to a supportive group of peers and mentors before you step foot on campus!
