You should buy more stationary
There is only one thing fun about GCSEs, and that’s the new stationary.
I asked my classmates what they used to revise, and more than one mentioned mind-maps. I personally found drawing on a map of the world with a whiteboard pen useful when I was trying to pinpoint regions. Anything you can do to make your study more interactive will help.
Buy highlighters in every colour. Stick those A2 multicoloured sheets of paper in your basket. Go on, get those scented pens. You deserve it.
