These get freaking hard really fast.

  There's a backstory to why they're structured this way that I'm not going to get into right now, but because "reasons", set #1 has a specific challenge (#6) that is somewhat tricky to code; we did that deliberately, as a qualifier. You should absolutely do the challenges in the order we give them, but the learning curve is a bit more gradual if you defer #6 until after Set 2.
