Finals Week-February 1-5

To All of my Classes:

The Final Exam will count 20% of your overall grade. The way to do well on the final is to review all of the work on the review sheets given out in class. Wewent over all of the work on these review sheets.
Also, remember to bring your binders to the final exam. I will check them and assign up to 100 points for each binder. In other words, the binder grade is similar to a test grade.
There will be no extra credit for this week due to the final exam. There have been more than 80 possible ec's given this semester!
