Don't waste your money. I doubt very, very much that this would make a difference in whether or not they want to hire you. And if they don't, don't take it personally. Who they hire follows no rhyme or reason. Be honest, be yourself, don't think you're too cool for school, have a bit of a sense of humor, don't take yourself too seriously no matter what. Just send in a resumé with the truth and keep your fingers crossed.
