Learning ActionScript 3

Hi all developers, fans, designers, and kirupa members.
I am currently doing my practical work experience at North Development (unibet internal development company).

I have worked as freelance designer, and webdeveloper for some years but programming have never actually been my strongest side but now I have decided that to take my work and career to some new heights,
I NEED TO LEARN PROGRAMING.

So, I am familiar to HTML & CSS, have worked with the basics of PHP & MySQL and done some simple publications in AS2 and JavaScript.

So, I want to be able to creata RIA’s and the way I am going to do that is in Flash & Flex.

For Flex, I found this nice set of tutorials on ADOBE’s site:

WHAT I NEED YOUR HELP WITH IS:
Is there an easy, hands on collection of tutorials that takes me from start to a spot where I find confident in the language to create my AS3 applications from scratch?

XOXO
