If you’re going to take a course to prepare for your commercial sUAS testing, V1 Aeronautics is the place to do it. I originally did it through a website (which just provided glorified PowerPoint slides…no way of asking questions) which didn’t go so well. This was before we knew that Bryan offered classes. Wasn’t too confident when I went in for my initial exam.  Took the class through Bryan and passed with a much higher score than I thought and was incredibly more confident taking the exam. The lesson here is to stay away from online “classes” and take your class with V1. Much better experience and was a ton more fun than staring at a computer screen for hours.  Totally worth it!
