Twin Cities Drone School is an excellent resource for anyone pursuing Part 107 certification. I attended the in-person class and found the curriculum to be well organized and the study materials handed out were very helpful as well. Above all, Joel was very knowledgeable and personable. He was able to present complex concepts in an easy to understand way and even made it fun. I also made use of Joel’s online course at Top Flight Drone School and found it to be equally well organized and thorough. Using only the materials he provided I was able to pass the Part 107 test with a score of 92% – no small feat for someone out of college for many years. Thanks, Joel!
