Sport Pilot Talk

I've decided to get my Commercial & CFI Ratings.

Having been away from flying for almost 5 years, I seem to have forgotten most of the VOR, ADB & Weather Chart nonsense that's still on the FAA tests, despite everyone in the air using computers, iPads and GPS information.

Any suggestions on the best test prep programs available? If I remember correctly, I used the King videos for my IR. Any comparisons between the ASA, King, Jepp, Gleim or any others that are out there?

Thanks

The Gleim material is very comprehensive, and affordable (though admittedly dry - no fancy videos or production value, just good content).
