If you are interested in further, low-effort ways to boost your recall, you may benefit from the following strategies:
- Just dim the lights, sit back, and enjoy 10-15 minutes of quiet contemplation, and you’ll find that your memory of the facts you have just learnt is far better than if you had attempted to use that moment more productively.
- Test yourself. So-called “retrieval practice” – actively forcing yourself to remember information – is far more effective than passive reading.
- “Space” your studies, leaving a few weeks between the times you revisit material. Indeed, it’s often better to wait until you are on the cusp of forgetting the material to avoid “overlearning”.
- Talk to yourself. Simple describing an event cements it in your memory.
- Add variety. It can sometimes be beneficial to mix up and rotate the subjects you are studying, a process called “interleaving”, rather than studying each one in a single block.
