Obviosuly everyone will revise differently, so you may have to try a few different methods until you find one that suits you for geography!
But if I could go back in time, I wish I would have made flashcards on everything, It would’ve made me slightly know the content more. Hope this helps
You can use the number of given marks to guide your answer. For exam style revision sessions, make sure that you have answered the question fully. Make and refer to your notes. Purchase a few different revision guides. Test yourself on a weekly basis. Read the question properly and make sure you understand every instruction.
