Active recall beats re-reading
Re-reading notes feels productive but is one of the least effective revision methods, because recognising information is much easier than retrieving it — and exams demand retrieval. Active recall (closing the book and trying to write out what you remember, then checking) is uncomfortable at first but produces far stronger, longer-lasting memory. Flashcards, blank-page recall, and past-paper questions are all forms of active recall — prioritise them over passive reading.
