Supplemental Instruction (SI)

SI is a series of out-of-class study sessions led by a student who has successfully taken the class before. 

Supplemental instruction has been supporting students at UW since Fall 2008. 

Student Voices:

"Being able to work on the problems and then come together as a class was really helpful.  I liked that there were a variety of questions."
"Really helped me understand the content better and gave examples which helped during the test."

Practice

It's a great way to practice the material and work with other students to learn the content. 

"It was helpful working different problems than seen in class."

Earn Higher Grades

Students who attend SI tend to earn a higher overall grade in their course! SI works best if you attend the whole semester, not just before exams.

Learn from Expert Students

Students get the opportunity to work with a student who has successfully taken the class, learning tips for success and studying, as well as cementing important topics. 

HOW DO I GO TO SI?

SI is offered in the classes listed below. Students can register for SI Sessions by downloading the Penji App and opening "SI Sessions." Registration is not required, however. Students are welcome to just show up! Dates, times, locations, and other information are announced in class by the SI Leader.
