I've had two Saturday exams since I started uni.
The first was 9:30am til 11:30am , and we were away to Hearts that day, so I met my brother in Glasgow after it and headed straight through to Tynecastle, still with my ruler, calculator and pens in my pocket. We won 2-0 and I got an A for the exam, so it was a good day.
The other one was another morning exam last year, but Killie were playing on the Sunday anyway.
I have heard of folk having exams on Saturdays at 2pm, which would be a disaster. I have a recurring nightmare that I am going to have one at that time on the day of the Scottish Cup final or a relegation decider or something.
