Here is the inaugural revision tip of the day then!
It’s a really simple one – mark your past papers twice. I know that teachers tell you all the time that using the mark scheme to mark your own work is a good idea, it helps you to see where you’ve gone wrong, helps you to understand what the examiner is looking for etc. That’s all fine, but sometimes having an expert (that’s me, on the left there, obviously) mark your work objectively is better than your own subjective assessment of your efforts.
If you do a past paper at home, mark it yourself, then bring it in and get me to have a look over it. The thing that can most reveal your misconceptions and weaknesses is looking at how you have misinterpreted the mark scheme and been, sometimes, a bit too lenient with yourself.
Give it a try!
