Starting Point vs Beginner Track

Why is there both a “Starting Point” and also a “Beginner Track?” Is one even more beginner friendly than the other? Why are the boxes that are shown in both Starting Point and Beginner Track not findable in the list of Machines?

I think I understand a little more now.

These are “retired” machines, so when searching, I must be sure to not be filtering to see only active machines.

The Beginner Track includes both boxes and challenges, the latter requiring a VIP membership.

So it seems like working through the Starting Point machines is the most approachable “first step” for students and n00bs like me. Then, perhaps trying out the Beginner Track or other easy, active machines.

I would love to know a little more about the history of both the Starting Point and Beginner Track, though.
