Don't worry about Indoc stuff until you start class where they'll teach you what you need to know.
You'll want to start studying those Emergencies and Limitations once you can get your hands on one of the packets though, but don't sweat that too much either. You have all of ground school to pass the test if you have trouble the first time around(They literally let you retake it every day until you pass throughout the duration of the ground school).
