mind maps or revision notesWatch
With notes it would be clear and structured and it is the tried and tested method (write,read rewrite etc.) of learning.
i also use key word cards
One of my teachers said 'whats the point of taking notes when its all in the textbook
Besides, textbooks provide too much information, only about 45% of the content is actually asked in the exam, i.e. in AS.
(This is my own opinion)
btw thx for the feedback
