Early content in RSPEC Section?

I attempted the “bubble_sort” sub-problem of the “iteration” problem in RSPEC-2 and it looks like the solution involves a working knowledge of Classes–which, again, are further along in the course. I think I’m just going to move on to the next section and come back to the RSPEC exercises later, because so many of the RSPEC exercises seem to require material that hasn’t been covered up to that point.

Thanks for the feedback! We expect to release a re-ordered curriculum addressing this issue within the next few days.
