Yeah I definitely think 9am exams are the best-your mind is fresh, you've just woken up and you haven't had that much time to get stressed. That's why you people should have chosen to do a subject like psych hahaha (it's at a sensible time).
It could always be worse - you could be so preoccupied with your other exam that you aren't faced with having to *wait* until the clock ticks round.
For instance, you could be doing a physics exam while trying to retain some distant knowledge about the accounting exam you know you have to do an hour later -.-
For mid-years I had my physics exam the same day, and for end of year it was legal studies.
Or... even better... you could have a family friend suicide the same morning and even though you know your Nanna (who's being totally wonderful by driving you to skool so you don't have to walk 4.7km) is really upset (and doing her best to hide it), you have to push it out of your mind and focus on yourself.
My point is... stuff happens guys - make a day plan for tomorrow, but be prepared to roll with any of the punches thrown at you.
My advice... don't change your eating habits on the day, skim through your summaries and repeat things (definitions, acronyms, etc) aloud to yourself from problem or key areas, flick through your practice exams and take note of the little mistakes that cost you marks, take a look at the examiner's report from last year's mid-year (they point out common mistakes as well), get to school with at least a half hour to spare (so murphy's law doesn't have the opportunity to make you late), and when you get there don't talk to the panicky people or people 'smarter' than you coz they're likely to mention some obsure thing that you're not supposed to know that will make you panic because you think you ARE supposed to know it.
=> That includes going into any last minute, panic threads on VN - you don't want a panicky member's worries to heighten your own stress levels. Let the members on here who've 'been there, done that' allay their fears, and you concern yourself with your own needs. Tomorrow is about YOU performing your best - if there's ever a time to get selfish it's the day of an exam. Remember, some stress is normal and will help you work more quickly in the exam than if you were to take a casual approach. However, if you find your stress levels getting too high in the lead-up to the afternoon, then do something that makes you relax - watch TV, take a shower, go for a run, or chat to someone (who doesn't have an exam).
