Aptitude tests are test inate ability and Siy getting up late will not change that. Furthermore, you don't start each test until you are ready and you have seen the examples so you shouldn't have been rushed.
Siy did you actually get to the interview or did you withdraw after failing the aptitude ?
Also, the average improvement is only 10% for you second and final attempt at the aptitude tests so I would suggest you will never be competitive if your only branch choice is pilot. You should widen your choices if you really want to get into the RAF and consider some non-aptitude related choices.
Anyway, if you do come back to OASC I look forward to Interviewing you.
P.S. The AFCO's opinion only gets you to OASC. Once there very little notice is taken of the report since you often find that what the AFCO sees is not what the is evident at OASC and guess whose opinion counts more?
