How to Actually Use These
1
Don't just read — test yourself
Passive reading doesn't stick. Use quizzes, flashcards, and practice questions to actively recall information.
2
Past papers are gold
Once you've covered the content, past papers are the single best way to prepare. Do them in timed conditions, then mark honestly.
3
Check your exam board
Make sure you're using resources that match your specific exam board and specification. They're not all the same.
4
Little and often beats cramming
Spaced repetition works. 20 minutes a day beats 3 hours the night before — your brain needs time to consolidate.
