Summer SI Sessions will begin on May 31st! Students enrolled in SI courses will receive an e-mail from their SI Leader with instructions on how to attend, locations and times of SI Sessions. The SI Session schedule is also posted on the SI website, and on the Learning Center & Supplemental Instruction support group page on Fridays.

No reservations will be required to attend. All SI Sessions will be offered in-person. Some SI Sessions will be recorded for the Summer 2023, the link to view the recordings is at the top of this page.

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.
