If you want to get a preview of what's covered in the module, you may want to try the prequiz below. The quiz is scored in a way to let you know what part's of the math you already know and what parts you should focus more strongly on. The grade in this quiz is for your use only -- it is not reported to your instructor or anyone else.

If you decide to take this quiz, you should NOT guess if you're not sure. Just click the "not sure" button, that way you'll get a more accurate reading on what you already understand.

OK, that's a wrap.Click here to start the module!
