Product reviews for Fundamentals of Instructing (FOI) Ground School & Test Prep

The web page is well done.  Pretty easy to navigate, though not completely intuitive.

Very helpful and very informative. I passed with a 92 thanks to John and Martha. Highly recommend this course

covered the subject areas ok but none of the questions looked familiar.

King's standard is always upheld and thoroughly enjoyed my CFI course!

I've used King for everything from Private Pilot to CFI.  I appreciate the simplicity and thoroughness of the courses.  My wife just began her Private Pilot course and is using King.
