Question: what was the hardest set of exams that you have done?

For me, my third year at university was most challenging – we had these courses which contained strange new concepts – we had this one called ‘transport phenomena’ – the name enough is enough to tranquilise you – the lecturer made the mistake of failing to convince us at the start of the year that it would be useful and interesting – which made studying hard and concentrating on big fancy equations impossible.

Sadly, it turns out the subject itself actually is fascinating and useful, but I really only understood that fully about 10 years later – when I was motivated by the need to solve a real-world problem!
