Instructors at the college have told me they get so frustrated when people turn up and haven't got a clue where certain places are (not exactly, but the vicinity...)
I remember a Law question that was on my basic Law exam,it required you to know that Newcastle was more than 40km away from Norwich, if you did, you would realise that a flight plan would be required as the aircraft was IFR and weighed over 7500kg MTOW (please don't quote me on those figures!)
So a basic knowledge of worldwide geography is required and is expected of trainees starting the college.
Good luck to you all.
