So I'm back in the swing of things, graduating college in May and will resume flying for the first time since May of 2004. Luckily I've done lots of studying and my knowledge is all back up to commercial training.

I've been using a Gleim from 2003 to study for the commercial written, and figured this was suitable for preparing. Have the questions changed that dramatically from 2003 to now that I should be using a newer book?
