- 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.
