I have taken the King Schools' private pilot course many years ago and was familiar with their method of teaching. So I did not hesitate to purchase the drone pilot license test prep course. It met my expectations, as I feel I am thoroughly prepared to take the drone license test. Based on my experience, I would say this course is the most efficient way to prepare yourself to pass the test.
