01Active recall
Best for: facts and definitions
Instead of rereading, close your notes and try to retrieve the information from memory. The effort of remembering is what strengthens learning.
- Turn headings into questions and answer them from memory.
- Use flashcards, blank-page brain dumps or practice questions.
- Check your answers and focus on what you missed.
02Spaced practice
Best for: long-term retention
Spread your study of a topic over several sessions with gaps in between. Each time you return just as you start to forget, the memory becomes more durable.
- Plan short reviews 1, 3, 7 and 14 days after first learning something.
- Use a simple calendar or flashcard app to track reviews.
- Keep each review brief and recall-based.
03Interleaving
Best for: maths, science, problem solving
Mix different topics or problem types in one session rather than doing many of the same kind in a row. It feels harder, but it improves your ability to choose the right method.
- Shuffle questions from several chapters into one practice set.
- Before solving, name the method you’ll use.
- Review why each method fits each problem.
04The Feynman technique
Best for: understanding concepts
Explain an idea simply, as if teaching someone younger. Wherever your explanation becomes vague or relies on jargon, you’ve found a gap to fix.
- Write the concept at the top of a page.
- Explain it in plain words with an example.
- Identify gaps, revisit your sources and simplify again.
05Elaboration
Best for: deeper understanding
Ask how and why questions and connect new information to what you already know. The more links you create, the easier it is to recall later.
- Ask “why is this true?” and “how does this connect to…?”
- Compare and contrast related ideas.
- Use real-life examples from your own experience.
06Dual coding
Best for: visual and complex material
Combine words with visuals such as diagrams, timelines or flowcharts. Having two ways to represent information gives your memory two routes to it.
- Draw a diagram or timeline from your notes.
- Explain the diagram in words without looking at the text.
- Compare your drawing to the original and correct it.
