The CodeCademy Angular courses, which are lessons 35-38 on the Waypoints track, are confusing and not great illustrations of Angular's inner workings. Most of the projects included within the lessons are simple checklists with very unclear instructions that throw jargon around that isn't properly explained. It also barely explains what MVC frameworks are, something very important for learning why to use Angular.

I suggest replacing the lessons with the similar (and similarly free) Angular offering from CodeSchool called 'Shaping Up With Angular.js'. This is a much more step-by-step walkthrough of Angular that shows in detail how to use Angular to build a very nice app.
