i would apply whatever your feelings, i was never made oasc in the end for a few reasons and regret it every day.
Dont worry and be put off by people who say becuase you are questioning joining that its not for, its a way of life etc etc. You need to very carefully consider what you are about to do, it requires more commitment than anything else in life because it is a way of life and you must really want to become part of the RAF.
Attend the filter interview study hard attend OASC and lets see what happens.
Remember, you dont have to join if you dont want to. Although if i could do back two years i would.
