Product reviews for Instrument Rating Ground School & Test Prep

This course was extremely helpful.  Instrumental in helping me nearly ace my knowledge test.  Presented in a straightforward and enjoyable fashion.  Thank you for your help!

Studying on my own, I might have eked out a passing score.  But, thanks to the King Schools Instrument Rating Ground School & Test Prep Course, I had an almost perfect score.  And, I had fun while learning.  Thank you John and Martha!

EXCELLENT TEST PREP! I'LL BE BACK FOR MY COMMERCIAL CERTIFICATE!
