Letʻs finish strong!

Two more content discussions, then final student presentions.
Everyone is so excited to watch your final presentations. Please sign up for a [presentation time]
Attendance is mandatory at all remaining classes.
Come prepared by reading the book, and our discussions can probe deeper. This will make your homeworks, labs, and papers so much easier.
Remember that effort counts, and will be taken into account in the final grades. If your grade is on the borderline, effort will translates into a “bump up”. You show effort in many ways, including attendance and sincere participation.
