I think it's hard, maybe even impossible, to know what you're going to use when you're at the beginning of learning something. I would trust the course structure -- presumably people who are further along than we are know more about what constitutes fundamentals than we do, esp since after Fundamentals I and II it branches off into other styles. I'm guessing therefore that there is a reason for the material in Fundamentals even if we can't see it yet.
