RobinXe is out of date. His/her information about the FT is incorrect. The individual who insisted that individuals stopped at excellent is, apparently, no longer in post and the present incumbent is prepared to let candidates run till they drop. The FT has also been updated after a review of the level of fitness required for OACTU, and the number of shuttles required to reach each level has been increased. You need to get 11+ to achieve excellent and therefore gain 4 points toward your overall score.
Overall, OASC can afford to be very choosy and, as has been suggested throughout this thread, you will have to do well in all aspects of the selection procedure to get selected.
Good Luck to all on their way to OASC in the short term. It is not going to be easy.
Kipper.
