Next I would practice the summary questions, if there were any set in the textbook. Do some practice questions, practice makes perfect. To summarise the double page spread I made flashcards of the all the important facts. Very minimal notes on my flashcards so I had to try and remember. I also included things that I always forgot.
Lastly, after every topic, practice papers and mind maps! As i got closer to the exam, I practiced complete past papers and marked them using the mark scheme, underlining key terminology and correcting calculations until I understood every mistake and error.
