Supplemental Instruction is an academic enrichment program that targets historically difficult academic courses and offers free, peer-assisted study sessions to all enrolled students in a designated section of selected courses.An SI leader will present information about this program during the first class meeting. Students who enroll in an "SI" section may choose to attend free study sessions which are regularly scheduled, out-of-class review sessions held each week of the semester.Research indicates that students earn one-half to one full letter grade higher if they attend "SI" sessions regularly during the semester. To see which SI classes are being offered, call Tutoring and Academic Support Programs at (940) 397-4684.
