I'm very happy to announce that with the help of UAV Coach, I was able to pass the Part 107 drone pilot exam with a 90% score.
A couple of suggestions:
It's hard to guess, but I had never seen about 20-30% of the questions on the exam.
It is very important to learn the basis behind the rules and class material and not depend on memorizing the practice test answers.
Learn all you can and repeat and repeat everything you learn.
I am quite sure I would not have passed it on the first round without taking this course.
Thanks to Alan and Mike for always responding
