Flock,
Just some extra info, where ever you end up.
A 4 week PPL is alot of work so if maybe worth considering getting all your writtens out of the way first, that leaves you with just the flying to concentrate on. I did a 4 wk course and I am glad I did the exams first, other members of my course were locked away at night studying and the odd one (due to the fact they couldnt extend their course due to work commitments), went home empty handed and would have to return or finish off elsewhere!
Julian.
