OASC 'CANDIDATES' and WANNABES, PLEASE READ THIS THREAD FIRST!
Bridge
Although I don't know how the OASC selection system works, the one thing I would say is that even if you only got a "weakly recommend", it means that they think you have displayed the potential to make it through. You should take comfort from the fact that they have chosen not to reject you.
The way forward as I see it is to either get accepted or if they reject you this time, then find out what went wrong, reapply and make sure that in the interim you've addressed the issues raised and go back with a stronger performance.
