Not too hard to get all A's in bowling, badmitten, and aerobics - actually probably need atleast 1 more class to become a full-time student - so how about scuba diving as well?
You really think players like John Wall and Demarcus Cousins are going to take classes that take effort when they know they'll never complete their first year of college barring injury? Half of these guys take the easiest majors at school - and those are the 4 year guys - not the one and done types. I certainly wouldn't be taking any math/science/english/etc if I was Wall - I'd be taking those electives and living it up.
