The King Course was the only test prep tool I used for the written exam. Passed on first try with score of 88. I had previously read the FAA materials over a two month period but found I wasn't retaining the information. The King Course solved that problem. I esp liked the ability to take the course on my iPad which made it much more convenient to squeeze in lessons during the day.
