Seems to be 1 thing there very strict on, as I failed mine on eyesight, you might get away with .25 but dont bet your life on it, go down and do it and see what happens, make sure you have a good nights sleep, and DONT drive x amount of miles then go and do the medical, with you being boarder line you might just blag it, but if you have been on the road for 4 hours your just asking for trouble.
Good Luck.
