@dxdydz why are you asking on your friend's behalf?
weird timing on his medical check up since you will usually get informed of it on a Thursday with the check up on a Friday. BTW the whole medical check up is probably a whole day's affair, with the candidate going for a check up with the eyes specialist, amongst others.
PS the results from the medical check up can really swing either way. ST medical may tell you that you are fine, but you may still get rejected, so there is almost no certainty until you receive the letter of acceptance.
And even then, you are still under probation for the next few years
good luck to "your friend"
