I am confused. I looked at the NAR website, and while there is a Jr. L1 Study Guide and a general L2 Study Guide, there's no general Study Guide for L1, or does L1 have no written test if you're over 18? I assumed this was like the FCC licensing for Ham Radio, where you need to pass a written or multiple choice test. And see a zillion questions here about the best L1 rocket kit, but nobody seems to be asking about the test, so I'm starting to think there isn't one. What's the dillio?
