Well, as i stated b4, our system goes: white, white w/ yellow stripe, yellow, yellow w/ green, green, blue, brown, red black. they each have a stripe in between. what we do is we have tips. its like a pretest, the first part is the form and if they pass they get a red tip. the 2nd part is combo techs and whatnot and then they get a black tip if they pass. Thats the pretest. when they get both tips it means they're ready to test.
