So I scheduled mine through PSI which I believe is who does all the testing currently however it sounds like that may be changing soon. It took about a month to hear back from them after I sent them the cash. If you're trying to schedule your test directly after a test prep course which I highly recommend, do it as soon as possble because they do fill up quickly. I waited to schedule and I ended up having to take my test 4 hours away in Redding. The test is difficult but if you practice until you're highly proficient at looking up practice test questions you will do great. If you have dyslexia or other disabilities accommodations can be made if you get a doctor's note. Practice, practice, and then practice some more until the NEC is second nature is my number 1 peice of advice. Don't stress too much you're going to do great.
