Product reviews for Flight Instructor (CFI) & Fundamentals of Instructing (FOI) Ground School & Test Prep Bundle

I've used King Schools courses to study for every written test from private pilot through flight instructor and have never scored under a 90%.  Hands down King has the best courses available to prepare for any written test you are studying for.

The online course provided excellent preparation for the AGI written exam.

Good self study course

John and Martha are timeless. They make aviation easy to understand in down to earth terms.

EVERYTHING I GET FROM THE SITE IS MORE COMPLETE THAN CAN BE EXPECTED.  MY HIGH SCORES ON EACH MODULE OR COURSE HAS BEEN A COMPLETE UNDERSTANDING OF THE MATERIAL PRESENTED.  A PILOT CAN TRUST WHAT HE IS GETTING AT A FAIR FEE AND THE OPPORTUNITY TO REVIEW  MATERIAL AT ANY TIME.  THE OPPORTUNITY TO UPDATE MANY OF THE COURSES IS AN OPTIMUM OPPORTUNITY TO STAY CURRENT!

Helpful material and worth the time to complete!

As a CFI student, this truly is the best course. I have used other forms of OGS (I will not mention which ones) but this is by far the best one. I was a little weary at first because of the price but it is worth every penny. I regret not using them earlier as a student pilot. You will learn the material so much faster and actually understand it
