There may be a lot of people in the system once recruiting starts but this shouldn't put people off applying. OASC has got to give the jobs to someone so i guess as long as individuals make themselves as selectable as possible then they stand a chance. You have been through the process before so should know how to best prepare yourself for another attempt; assuming you are still chasing your dream. If you are - don't give up on it! Equally, don't worry about the others that are in the system - they will be driven on by their own motivation!
