How to revise: 6 methods that really work

Many students revise by reading their notes and highlighting them. It feels like work, but research shows it does not help you remember much. The methods below take more effort, and that effort is exactly why they work.

1. Test yourself (active recall)

Close your book and try to write down or say everything you know about a topic. Then check. The act of pulling information out of your memory makes it stronger.

Ways to do it: flashcards, quiz questions, end-of-topic tests, or a blank page "brain dump".

2. Space it out (spaced practice)

Do not revise a topic once for three hours. Revise it for 30 minutes, then again after a few days, then after a week, then after a month. Each time you nearly forget and then remember, the memory gets stronger.

3. Mix topics (interleaving)

In a Maths session, do a few questions on fractions, then area, then equations, then back to fractions. It feels harder than doing 20 of the same type, but it trains you to spot which method to use. That is exactly what the exam asks you to do.

4. Explain it (elaboration)

Ask yourself "why?" and "how?". Why does a bigger surface area speed up a reaction? How does the heart move blood around the body? Explaining links ideas together, so you remember them as a story, not as loose facts.

5. Draw it (dual coding)

Turn notes into diagrams, flow charts and labelled sketches. Words plus pictures are easier to remember than words alone. This works very well for processes such as digestion, the carbon cycle or electrolysis.

6. Use past papers and mark them

Practice questions show you how the exam asks things. Always mark your work with the mark scheme and fix mistakes. The marking is where most of the learning happens.

What to avoid

• Rereading notes again and again.
• Copying out notes neatly without testing yourself.
• Long sessions with your phone next to you.

In short

Good revision should feel a bit hard. Test yourself, space it out, mix topics, explain, draw and use past papers. Short, regular sessions beat one long cram every time.
