Like i said, i think many will fail this initiation, and be cut off is a big possibility, but We cant be sure of all ... Yea i think they will only accept only a few for the 1st Year, but who knows

I think most of weapon will use Dust, its apparently a common thing in RWBYverse, And the main weapon to Fight Grim, its logical to use Dust To Fight against Grim Monsters
