For revision I mainly do past questions by topic to identify my strengths and weaknesses. Looking at the mark schemes also teaches me how the
examiner wants the answer to be phrased.
For History I make a lot of mind maps to remember dates and events and terms of treaties etc. Timelines also help, as they allow me to visualise the procedure of events (which will also help you as you're a visual learner).
For Literature just go to websites like Shmoop and Sparknotes to brush up on the summary, themes, analysis.
Music brush up on your terms and listen to loads of pieces.
