Yes.
I know, convoluted answer but here's the reasoning. Doing well in school, holding down a part-time job, being fit...all that "mimics" the hectic, frenetic life of an SA cadet. They go to school, they have military obligations (duties), they have intramurals, etc...etc. And they're required to balance all of that and other things equally well.
Might as well show you have all that NOW.
