The best place I have found to learn about Angular is http://egghead.io . The videos are really clear and concise.

Many of the more confusing Angular fundamentals that many tutorials like these don't stress egghead.io has short 2 to 3 minute videos explaining in very clear terms.

PS. I know I sound like a shill, but I have nothing do with egghead.io other then I've found them immensely useful.
