About SI for this Course

CHEM 331 stands apart from other chemistry courses with its unique content. This can be a stumbling block for students, but it's also an opportunity to explore new ways of understanding the chemical world. My sessions will focus on looking at material in a variety of ways with an emphasis on the underlying principles. I'll do my best to post worksheets/notes after sessions, but you'll get the most out of them if you actually attend! I am more than willing to answer any questions sent to me, and I prefer if you email me directly at

. Looking forward to seeing y'all at SI!
