Not much. And that's a shame. XD
Oh dear, time usually is something to keep in mind while doing an exam, unless it's a subject you tend to bumble on it's better to just get it all out of the way as quick as you can. I remember when I was doing my exams, finished them in about an hour and waited 30 more minutes just for the exam session to end, so it was fun drooling on my desk sleeping.
