Supplemental Instruction

Supplemental Instruction (SI) is a FREE service that provides regularly scheduled, out-of-class study sessions.

SI sessions are led by trained students who have previously taken the course and attend every lecture. They are well-informed about what's happening in the course and maintain a strong understanding of the course content. SI Sessions—open to all students in the class—review important course concepts, predict and practice test items, develop test prep strategies, and discuss readings.
