Product reviews for Instrument Rating Ground School & Test Prep

The video tutorials are just great. I prefer that method of studying over the scripted versions. Thanks for providing such a wonderful program.

The website is easy to use.

I would give your websiet  five stars.

I passed my instrument written with 88% on my first attempt!  Thank you John and Martha, your online instrument knowledge course did a great job of preparing me for the written test!  I think the online course can be updated with fresher videos and soundtrack but otherwise the information is there!  Being able to print course notes was a HUGE asset!

This course was amazing! I never would have passed this test without John and Martha's help. I can't wait to get to my next rating so I can use the King's courses again.

John and Martha are polished, effective instructors.
