I did the 11.30 yesterday in the gym on a treadmill. Would the 11.30 be enough to get me in?
Perhaps the best way for me to understand what level of finess I need to be at is the level they require from you on the bleep test. What level do they want?
No, frankly. Can't speak for OASC, but it would not get you through a FamVisit prior to IOT [unless you were in your 30s].
If you're not scoring level 12 during the course [again, it differs with age] then you'll suffer. But unless you knock 2 minutes off your 1.5 mile time, you won't get there to find out.
Let's not forget though, that physical fitness is only one part of the process, if you're useless in the interview, perform poorly in the exercises and discussions or come across as a bit of a numpty, you won't get in.
