To follow up what Jeremy said, the at any time the UDE rep. testing can refuse you the test. Luckily enough I was able to take the test up at PCNY from James Lee who was giving the tests out. I didn't pass it, but a 70 on it is I guess respectable when you consider how green I still am to judging VS, if I had read over the Comp. Rules one more time before taking the test and hadn't had chosen to take it at a time that only gave me less then an hour to take it (I had joined the 10K that day and the 10K was about to start as I was finishing up the test, taking away any time I would have used to go back and re-read as I normally would do).
I'll have the chance to take it again this weekend hopefully as I'm judging the 10K in Charlotte. I'll update you guys on how I do when I get back. But basically I'd say hold off on testing unless you are more then sure you could pass it, it doesn't hurt to take it to see, but if you walk up to the guy and say "Yeah, I want to test for L2." and they ask you "Ok, why would you want to?" and you just say "Because I want to see if I can pass it." They'll probably turn you down.
But yeah, read over the Comprehensive Rules, don't be dyslexic like I am and misread a question. I got one question wrong because I misread it leaving out an entire sentence from the question, that hurt me a little, but yeah, I know it won't happen again. I just gotta read more careful next time.
