I'm just curious. Of the seven stated end goals of the Foundation course, which is the hardest? Which is the easiest? To define "hardest", think of how they would be rated hypothetically based on similar principles as gymnastics skills are rated for competition purposes.
I would think that SLS is the easiest one. Mostly because I can see myself managing that one the easiest based on how things are going for me.
I would guess sPL is the hardest, but that's just a guess.
