I don't know if your association assigns by The Arbiter, but they have a quiz section on there. http://www.thearbiter.net/

Also, not sure if you're affiliated with IAABO or not, but you can go to http://area9officials.org/
the last link on the left side of the page is past tests for review you can click there to take old tests (2004-2007) & check your answers.

NOTE: Rules change season to season & may affect your answers.

Hope this helps.
