Well, the proof on how good the course is or is not, simply boils down to test results. In my case, I made a 95% and I'm pretty sure it would have been a 100 except for those few super tricky questions. Bottom line, I'm very glad I took the course. In addition to this wonderful course, I recommend reading the 107 Advisory Circular and being very familiar FAA-CT-8080-2G that will be used throughout the test.
