A supportive space to learn, connect, and grow.
Supplemental Instruction (SI) creates supportive, peer-led study sessions within select Writing, Math, and Chemistry courses. Students work alongside classmates in a relaxed, structured collaborative environment where they can talk through challenging material. SI sessions give students time and space to practice, connect ideas, and feel more confident with course material.
