About SI for this Course

Physics 221 can be a difficult class; SI is here to help. Each session will last 50 minutes and focus on mastering course concepts through problem solving and group collaboration.

A typical session will cover material from the previous lecture and will mainly consist of problems from old exams.

If you have any questions either about material covered in lecture, past worksheets, or practice problems, I will be more than happy to help; speak to me either at one of my sessions. Additionally, I will be attending class, so feel free to come talk to me before or after the 10AM lecture.

I look forward to sharing my knowledge of physics with you all!
