522581........ Mines been and gone lol, so nope it's a fact some kids actually don't want to go for lots of different reasons some who do go do not develop as well as if they had stayed at their home arena, others thrive, it's very very individual, and it's not the end of you do or don't go THATS what I'm trying to say.
Looking at some of the girls up there now, the associations they have come from (not talking about the WNBL women) they don't have a lot to offer if they stayed there so Cof E is a good opportunity, swap that to the boys and some who have chosen to go to college early will get more benefit from that than choosing CofE now.
But you cannot ignore the fact that if an athlete is already at the institute they are 10 times more likely to get a spot in a national side than the ones who don't go, they are after all under the daily watch of the selectors.
