A few weeks ago I used angular to create a sample app. That was a good experience. In keeping with learning more Angular, I came a cross a podcast blog Adventures in Angular. The first episode i listened to was http://devchat.tv/adventures-in-angular/angular-meetups-with-matt-zabriskie-and-sharon-diorio . This talk had training videos sessions:
Meetup Angular and bootstrap - see Plunkr
Utah Angular user group
Testing with Angular
Pluralsight has training on bootstrap 3 as well.
