The biggest problem that early students have is actually getting distracted by too many resources because it's so easy to get sucked down a million educational rabbit holes and never actually make real forward progress. I hear it all the time.
Many of our students start from the beginning and work through the curriculum in order but more tend to cherry pick lessons as needed to fill in the gaps in their knowledge. That's fine too and it's why the whole thing is available at once. The important part about having the path laid out, though, is that it keeps you accountable for your progress -- you know when you're getting off-track because you can see each piece of knowledge in the context of the bigger puzzle. For many, that's what they need to keep them focused.
