Great class! they run you through the basics and have you do excercises on the site itself at the end of each chapter.
when you submit the code it checks the code and gives you hints if somethings wrong.

Very through and easy to understand.

Seriously folks, if your just starting or even if you think you know everything, you still might want to watch some of this.
