The test is 100 questions true or false. Not sure where you can find a sample.
I just started officiating high school and youth games a couple years ago Brandon. My advice is to join a local officials association, read the rule book along with corresponding case book topics, then read it again. Your local official association probably has some kind of program for new officials, and can get you set up to work some scrimmages. Along with the rulebook here are some links with tons of valuable information from powerpoint presentations to word documents. I think you'll find some good info here. Good Luck. Work Hard.
