I expect that there is a rather wide range in the backgrounds of this class. Therefore, I am asking you to spend a few minutes answering the following questions so that I can begin to see what review material may be required. You are on your honor to answer the questions without recourse to any other materials.

Click on the answer bar to see the choices.

As soon as I record a "tick mark" by your SSN, I will remove the SSN from the survey. Your responses will not influence your grade in the course.

If for some reason you can not transmit this response, print out the questions, answer them and put the responses in my mail box in room 312 Science Research.
