About Supplemental Instruction

  1. Fun, informal study sessions
    Supplemental Instruction is not about lecturing or re-teaching. During these sessions, students master content by playing games and participating in activities with their peers. These activities are designed to simplify content and approach class material in different ways.

  2. A FREE way to get better grades
    Students who participate in at least 3 Supplemental Instruction sessions between each exam score, on average, more than a FULL letter grade higher than students who don't come. Students who participate in Supplemental Instruction are also less likely to withdraw from their course!

  3. A more effective use of study time
    Supplemental Instruction leaders are students who have already taken this class and passed with a high grade. That means they know exactly what it takes to be successful in this class! Participating in a Supplemental Instruction session is studying, because your leader will show you new ways to learn and remember the content, and also teach you tricks like how to take better notes or study for exams.

  4. A place to make mistakes
    Supplemental Instruction sessions are voluntary and anonymous. Your instructor won't know who comes to Supplemental Instruction. This makes them the perfect place to test your understanding and make mistakes without it impacting your grade! Supplemental Instruction is a place to learn and practice hands-on with your peers, not to be embarrassed if you get something wrong.

  5. All about you
    Come when you like and stay as long as you can - even if you can't make it on time or stay for the entire session! Bring your questions (and even your lunch) to your Supplemental Instruction sessions to take advantage of the hands-on learning here.


Is Supplemental Instruction just like tutoring?
No. Supplemental Instruction is different than tutoring. In a Supplemental Instruction session, you and your peers do the work! It is an opportunity to get hands-on with the material and learn it your way. In some of our previous sessions, students have made paper models, played games on the white board, build structures out of legos and play-dough, and drove race cars through the various parts of a cell. These are just some examples of what we do here.

Also, your Supplemental Instruction leader won't answer your questions like a tutor will. Instead, your leader will guide you and the others in the session so that you can answer your own questions and learn what to do when you get stumped. The activities you participate in during your sessions will cover the most difficult material of the class so that you're prepared on test day.

Of course, the best part is that you can access all learning support services! You can come to the Supplemental Instruction sessions to get practice working with the concepts from class and meet with a tutor at one of the Centers for Academic Success locations—visit for more information.
