What is SI?

Supplemental Instruction offers free, peer-led review sessions for historically difficult courses. SI Leaders, are peer students who have demonstrated academic mastery in the course, prepare weekly review sessions by attending lecture, taking notes, and meeting with the course instructor. Sessions offer guaranteed study time and additional support outside of the classroom.

Research indicates that students who attend SI sessions on a regular basis earn half to a whole letter grade higher than students who do not attend SI sessions.
