  • Posted on 09/20/2011 by Lingling
  1. I updated the presentation schedule for this semester. If you have any problems on your assigned topic/date, you need to let me know as soon as possible. Missing the presentation will affect your grades for the course.
  2. The slides for the students' presentation will usually be updated a few days before the actual presentation is given. The ones that are online now are examples from last year. Please check the dates on the slides to make sure that you are printing/downloading the newest version.
  3. Please email me your ppt slides and three questions on your topic (one hard, one medium, one easy; with your answers to the questions) at least one day before your presentation.
  4. Feel free to discuss your assigned topics with Rizzo lab members.
  5. The first quiz is going to be next Monday (09/26/2011). Please be prepared. The quiz will be based on lecture slides and class discussions.
