You’ll have plenty of time so DON’T rush.
Read through paper before starting – parts of your brain will start
thinking about later questions whilst your on the easier ones.
Read each question carefully and make sure that you understand what
it’s asking you to do before you start answering it.
When you’ve finished an answer, check back to make sure it seems
sensible and answers the question.
Draw any diagrams or graphs using a pencil so you can rub out any
mistakes
If you get stuck, think for a minute, if no joy move on to next
question. Your brain will keep mulling over the stuck one.
If you want to replace a mistake, just cross it out so the examiner can
still see it. Don’t obliterate it.
When you get to the end of the paper, go back and retry the ones you
got stuck on. Don’t leave any question unanswered if possible. Go
with a hunch or have a guess. The only questions you are certain to
get no marks for are ones you haven’t tried.
Now go and nail it!!!
