Usually you will remain but the ActionScript Level 2 stand (because the nice easy going ... you must learn nothing from programming) and that's a shame.
who "survives" the tough entry (not on classes, objects, and so despair!), comes with the good examples that can be used quickly to class results and the projects remain future-proof.
The new event handling is super explains.
The material is absolutely not for beginners even for advanced users with programming experience, it is very (too?) Fast to the point.
Recommended as a preliminary exercise:
Flash CS4 (perhaps there already CS5?) Foundations with Todd Perkins of Video2Brain
Conclusion: 1 star deduction because many will be explained too fast, a must if you want to stay uptodate.
