Hello all, As many others, I am very excited about the Part 107 and have been waiting for it for a while. I have a few questions that hopefully the community can answer now that the dust has settled. I am currently only registered as a hobbyist. 1. Where and when can we sign up to take the knowledge test. I know where my nearest FAA center is, but where do we sign up? 2. Have mock exams/ list of things that will be on the exam been released yet? A "Study guide" if you will. If so, where? 3. As I am currently a hobbyist, can I apply for this certification at the same time or do I need to somehow unregister as a hobbyist as well? 4. What is the estimated cost of the entire process? If I remember correctly from the very beginning, is is only the cost of the exam? Thank you all! Fly safe.
