A few things over the last week or so I have understood.



1) "Try your best". Undoubtedly, teachers will continually tell you as you walk into the hall, Good Luck (Always nice to hear) and Try Your Best. Because without them telling us this at least twice per exam, we may have all simultaniously chosen to fail them, because noone told us to try!



2) Do NOT revise for the RE exam. It is compulsory and pointless, spawning the facebook group: "Im going to do some RE revision LOL JK noone revises RE".
The obvious exception to this being the geeks such as I, who chose to do Full Course RE, making it a chosen subject and therefore revisable.



3) Your phone is a genius. It will in fact go off the second you must be silent, whether it is on silent or not. And if you turn it off? Well, better take out the battery, because it will of course turn itself on if you don't.



4) Numbers are magical and change. Seriously, You'd better check your seat number and candidate number every three seconds, because any longer than that and it'll change around.



5) Facebook is the enemy of revision. If you are serious about your revising, don't check it. Like, block the site if it's possible, just keep it as far away from you as possible. Oh, and make sure you don't end up in an accidental battle of bejewlled scores. It becomes somewhat addictive.



6) Msn can be helpful, but is somewhat troublesome. DO NOT get drawn into a conversation about how hard revision is or how rubbish your teacher is. Whether this is true or not, its not helpful to anything. It is in fact an amazing way to procrastinate.



7) Men, whether you are having a hard time or not, pleasing yourself because you finished half an hour early is not cool. You're still in public. Keep those hands out of those trousers please.  (My second exam, the kid to my left. He's lucky i couldnt remember his name)



8) You must make sure you have a spare pen. Actually, forget a spare pen, just take the whole bag of black pens. You never know when one'll run out.



9) If you revise it, guaranteed it will not come up. Exams have a lovely way of asking questions on the one bit you werent too sure on, and then making the question worth like half the paper.



10) The invigilators, a) Will always have a stick up their bum. I have met just two nice invigilators. And i've met a few. b) Always have a twitch! Now, this is usally fine, but when you finish an exam and look up to see someone twitching, and you have five minutes left, you will continually be drawn to the twitch, and then consequently feel guilty for staring at them. Oh, and a blackberry is not a blueberry.



And not a rule, more of something that occurs to me, that writing rules of the exam season is the perfect way to put off doing maths revision.
