What I wonder is how come 1in of snow stop people going to work, but you still manage to get to the ski slopes after 1ft of the stuff has fallen.
Sorry to state the obvious, but given the hassle involved in (re-)sitting the exams, I stayed within walking distance overnight so that if, e.g., I pranged the car on the way there, I could just leg the rest of the distance and let the traffic cops worry about anything else. Very conveniently, the CAA have their own medical centre on the premises so one could get any injuries treated before entering the exam room.
Proper Prior Planning and all that
