Supplemental Instruction (SI) is a peer facilitated program focusing on historically difficult courses. SI sessions are voluntary, regularly scheduled, informal review sessions in which students review course content and study skills while working together. The sessions are facilitated by SI Leaders, who are students who have previously done well in the course and who attend all class lectures with the current students. SI sessions are available three times a week for each targeted course. 

Currently, the SI program works with courses in Biology, Chemistry, Computer Science, Math, and Physics.
