we got like maybe 6 hours until this test, i recommend you spend half of that blurting
get a few A4 sheets of paper, at the start of each new one write topic 1 - 9, then closed book write everything you possibly can onto that bit of paper about that unit (i do bullet points, definitions, models, theories, calculations etc..) once you completed a unit and you dont think you could add any more, open your notes or book and add the things you got wrong or forgot to add.
do this for every unit, you have to strengthen your recursive learning skills e.g bringing it out of your mind over putting it back in
