The course is out of date.
Everything is mostly up to date, but the course works with angular 1.2 but not 1.4. There are only a few areas where this matters. A course update should be published at any time.
Module 1, "Demo: Hello World in Angular" doesn't work.
In the module on routing, HTML5 routing requires a tag. See this: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/base
You may have some difficulty in the testing module when following along the section on end to end testing.
