Hurry, you are late!
I am not sure what the process is like for Washington. In Oregon, we have to take a "class" wherein the instructor tells us exactly what you are asking.
I know that there were signs posted in the Sheriffs office when I went in advertising CC classes available. I saw signs posted at Keiths Sporting Goods also advertising CC classes. I ended up taking my class at the local community college. It was $35 and well worth it.
I would look into a local CC class (if you have them) and take said class.
