I bet you memorized the eye chart too didn't you...as the saying goes "If you ain't cheatin' you ain't tryin'"
No. They have countless lines of 10 characters so that would be impossible. But the color test is supposed to be like each plate is recognized in 3 seconds or something. If I usually take 5-7 on the more "difficult" ones, then seeing them beforehand allows me to recognize it instantly instead of having to stare at it for a few seconds to get it.
But ya, if you ain't cheatin, you ain't tryin.
