Trying to do your OU whilst sitting in a damp tent in Denmark...
Luxury! I did one of my OU law exams in a non-airconditioned portakabin at Basra, where the EdO invigilating gave one of the more memorable exam briefs I've had:
"In the event of rocket attack, don helmet and armour and take cover in the corner. I'll time how long until the all-clear, add that to the end time, and make a note on the invigilator's report form."
