I decided to try the Instrument Written course after I saw several previews of Martha and John King's series on YouTube and I was very happy with what I purchased! I think it's absolutely necessary to understand the basis of the knowledge exam's questions, especially for the written. I'm by no means a student that can absorb knowledge efficiently just by reading it, so getting the graphic explanation was a must. I did the Sporty's course for the Private Pilot several years ago, however it could get very dry for me. I think that the Kings have a natural talent at presenting these courses and it clicks much better for me. The question database is decent with the King's, but I highly recommend a secondary course like the Gleim or Sheppard Air (Sheppard Air has by far the most up to date database, but Gleim has better software). The reason I say this is because the FAA will often reword questions and add new, more confusing questions to their database in order to fool even the most experienced pilots. Although King Schools has an adequate database, it may not be enough to get a 90 depending on what the PSI/CATS gods randomly generate for you. However, I don't believe using just the Gleim or just Sheppard Air would be enough to pass unless you're an extreme memorizer. To each their own, and I definitely believe in the King system!!
