Supplemental Instruction

Supplemental Instruction tutoring consists of interactive out-of-class study sessions that reinforce and clarify what you learn in class. During a session, you can ask questions and practice completing the course material. By participating in an SI session, you can retain more information than you would by studying by yourself.
