Product reviews for Commercial Pilot Ground School & Test Prep

Thank you John and Martha!  Great Commercial Written course that covered exactly what I needed to know!

This is my third test using King.  Passed easily every time.

It took me years to finish preparing for my commercial written, the King Schools online course was always available and frequently updated.  The recently updated iphone app was instrumental by allowing me to take practice questions whenever I found a few minutes of time.

There is no finer or more complete ground school and test prep course available, than King Schools.
