About SI for this Course

Supplemental Instruction is a resource intended to hone your abilities in your respective classes. Each session is about 50 minutes and will target materials from the lectures.

In my sessions, I intend to review the content covered in the preceding lecture and solve example problems both individually and in groups to build confidence.

I hope to see you at sessions throughout the semester!
If you have any questions, please don't hesitate to shoot me an email through the SI website.
