PE4_Flash Action Script 3.0

I am fairly versed in basic animation and simple button and menu operations for building websites in flash, but I decided to be brave and explore flash's greater power and functionality in its Action Script 3.0.  I would like to have the skill to develop games and greater interactivity within flash.
I'll be watching the Flash Action Script 3.0 Essentials Tutorial with Todd Perkins on Lynda.

So far I've gotten through chapter 3 of the video tutorials. (About an hour and half of videos)
My impressions so far is now I remember why I didn't finish the computer science minor in my under graduate degree!  Yikes it's been pretty difficult to follow, even though Todd Perkins does a pretty good job at explaining some difficult concepts in simple language.
