I know you're anxious, but the placement test is just a way of getting you into classes
that are the right  level so you can be successful.  Just relax and do your best ....

fwizbang · Answer

About the worst outcome of a placement test is for you to be placed in classes 
that you're not ready for. I'm still happy to help you though. Do you know FOIL?
