Unfortunately for everyone who has double exam days we'll just have to take it like a champ and suck it up. u_u If you prepare well enough in advance, you shouldn't have too much of an issue with the two exams. It's only when you cram that you'll have issues arise since one subject will be inadequately prepared. Though, do keep in mind that it's 6 hours in an exam room, and make sure between the two you get out in the sun, have something to eat, relax, clear your head and get back into exam mode. Good luck to those battling the double exam days of doom (thankfully I'll only suffer 5 hours in a day, Legal and History Extension!). Remember, prepare EARLY!
