What is the difference between what you would learn, practice, and drill during your HS and collegiate wrestling years vs. what you would learn, practice, and drill going from BJJ white belt to an upper belt? I only know BJJ where you generally learn a variation of the following in a class: top position hold down, bottom position escape, submission, submission escape, drill, freeroll, etc. But what do you learn/do in a typical HS wrestling class then later college? Are you just taught takedowns then everything else you learn through scrambling and wrestling (freeroll)? I'm curious how what you learn and how practices are different for BJJ and wrestling.
