Supplemental Instruction (SI)
Supplemental Instruction (SI) provides regularly scheduled student-facilitated study sessions for traditionally difficult courses at Case. SI sessions are free and your participation is completely voluntary. Attending sessions allows you to ask questions, review notes, practice problems and prepare for exams in a relaxed environment.

Sessions are led by SI leaders -- students who have successfully completed the courses, are recommended by professors, and trained by ESS. During the sessions, SI leaders will facilitate an activity related to recent material covered in lectures. The goal is to involve students with material and introduce good study skills and habits. Some activities may include practice quizzes, vocabulary building, review sheets, or collectively working on problems. Because you will be working on course material, make sure you bring your book, notes, and any other material you may need to use as a resource.
Depending on the number of SI leaders for your course, there may be anywhere from two to six 90-minute sessions per week. Consult the complete SI schedule for more information.
