"I started my journey to obtain my part 107 remote pilot certificate by pulling up material from the FAA website, watching various YouTube videos, and googling various practice tests etc... to be honest, it got very frustrating (am I studying the proper material? what info am I not studying?). I then discovered the Drone Pilot Ground School. I found the information to be concise, comprehensive and well organized. After purchasing the course, I spent less than a week going logically thru the course before I signed up to take the FAA Pilot Test. I passed with flying colors (98% and only spent 58 minutes out of the allowed 2 hours). The Ground School course had properly prepared me for the material and for the Test: there's a number of section quizzes, final tests, cram sheet etc which focuses on Airman Knowledge Testing Supplement (which is also used on the FAA Part 107 Test). While going thru the Course, I did have a few questions that I emailed Alan/Mike; they responded back within 24 hours... Bottom Line: I highly recommend this course. Plus I can now refer back to the material whenever I want. Even though I have passed the Test, as I have more questions, they continue to help me out..."
