Rereading notes feels productive, but it is one of the slowest ways to memorize. Memory researchers have found methods that work far better, and most students never learn them. This guide shows how to memorize faster with 12 techniques, from simple self-testing to the memory palace.
In this guide7 sections
The two most powerful methods
- Active recall. Close the book and try to retrieve the information. Each attempt strengthens memory. See our guide to the active recall study method.
- Spaced repetition. Review the same material over increasing gaps (1 day, 3 days, 1 week). See our spaced repetition schedule.
Organize the information
- Chunking. Group information into small sets: phone numbers, dates by decade, terms by category.
- Make connections. Link new facts to things you already know.
- Use concept maps to show how ideas relate.
- Explain it simply. If you can explain a concept to a younger student, you understand it.
Memory tricks
- Acronyms. Turn a list into a word, like ROYGBIV for rainbow colors.
- Acrostics. A sentence where each word’s first letter matches the list.
- The memory palace. Picture a familiar place and “place” each item in a different room.
- Visual images. Turn abstract terms into vivid pictures.
Habits that support memory
- Sleep after studying. Sleep helps the brain consolidate memories.
- Interleave topics. Mix problem types instead of practicing one type in a block.
Which technique for which task
| What you need to memorize | Best techniques |
|---|---|
| Vocabulary and definitions | Flashcards with active recall, spaced repetition |
| Lists and sequences | Acronyms, memory palace, chunking |
| Formulas | Practice problems, explaining each variable |
| Dates and events | Timelines, chunking by period, connections |
| Concepts | Concept maps, explaining simply |
A sample memorizing session (30 minutes)
- 5 min: read the material once and chunk it.
- 10 min: make flashcards or a question list.
- 10 min: self-test, mark misses.
- 5 min: review only the misses.
- Repeat the self-test tomorrow and in three days.

Frequently asked questions
What is the fastest way to memorize something?
Combine active recall and spaced repetition: test yourself, then review again after increasing gaps.
Is rereading notes a good way to memorize?
Rereading feels familiar but is less effective than testing yourself.
Does sleep help memory?
Yes. Sleep helps the brain consolidate what you learned during the day.
Pick two techniques, such as flashcards with spaced review, and use them for your next test. For exam season, see our guide on how to study for finals.
