You're missing the point of a placement test. It is a test to do just that, place you in the appropriate class based on how you scored on the placement test. If you do not know how to do a problem, then you don't need to be in a class that has those kinds of problems. Simply take the test, answer the questions you do know how to do with your current knowledge and then accept the class that you get placed in. You will be much happier being in a class that is based on your current skill levels instead of trying to learn concepts now and risking being placed in a class that is dealing with concepts that you struggle with.

miles per gallon

Do you know that rates like this are ratios?

miles per gallon = miles/gallons

That is, miles-driven divided by gallons-used (they gave you these two quantities).

:cool:
