It could be worse, last year i had 6 exams on one day, all physics AS in morning and all econ in afternoon.
To make things worse, i was taking the exams at different places, so i had about an hour to get from one college to another via public transport. In fact there was quite a bad crash near where i had my AM exams while i was taking them, which could have caused delays, but fortunately for me, it was only gridlocked in the opposite direction!
