I'm a gap year student looking to sharpen my skills before studying history at KCL

I will use the methods that worked for me in getting a 9 at GCSE and (provisionally) an A at A-level history. This entails learning the content through active recall and flash quizzes as this is the best way of learning things. I will also teach to the exam by deconstructing the questions to make answering them much easier and encourage as well as recommend further reading.
