• Mon/Tues 2/11-2/12:  Check off problems 1-5 and go over.  Circular Motion Lab.  Universal Law of Gravitation.  Do problems 1-8 on 7+8 Worksheet for Wed/Thurs.

Final Exam Guidelines

1.Bring pencils, paper, calculator, and something to do quietly when you are done.  For this class you may also use a 4" x 6" (max size) note card with notes on both sides.  Remember that it needs to be hand-written and will be collected at the end of the test.

2.Go to restroom BEFORE the test!  No bathroom passes until after you are done, and then 1 at a time

3.NO CELL PHONES OUT PERIOD!!  Bring something else to do.

4.No talking until EVERYONE is finished.  This is basic courtesy to your classmates.

5.Cheating on any part of the test will result in a zero.  Don’t do it!

Finally, get enough rest, eat healthy food, and try not to stress too much about the test.  You will be okay!
