If you are receiving a PPP are you eligible for concessions if you choose to study? If so, does anyone know what sort of concession you receive?

I've just done the estimator on the c/l website and if their estimate is right - i'm finacially better off not going back to work however i'd like to go back to study. So even after paying CC fees, i'm still better off (i think anyway- depending on how much the course is LOL)
