Study tips
- Use spaced repetition: review notes after one day, three days, and one week.
- Practise with past papers under timed conditions.
- Explain a topic out loud as if teaching it; gaps become obvious quickly.
- Sleep matters more than one more late-night hour of revision.
"Little and often" beats cramming for long-term recall.
