Supplemental Instruction (SI) is an additional resource attached to courses that are generally more difficult for many students. It is not extra tutoring for weak students; it is additional meeting time outside of class time where students will learn from other successful students how best to prepare and learn in particular courses. For example, your SI student leader for a specific History class is a student that performed quite well in that course and is comfortable working with other students to help them prepare for the class. This resource is offered in selected classes for no additional fee. We strongly encourage you to take advantage of Supplemental Instruction.
