To memorize faster, reread less and test yourself more, spacing your reviews out over time. It's counter-intuitive: rereading feels like learning, but it's the effort of retrieving an answer that really makes it stick. Here's a simple method that comes down to three habits and ten minutes a day.
In short
- Testing yourself (flashcards, writing) helps you remember far better than rereading.
- Reviewing a little every day is better than one long session the night before.
- Break things into small lists of 10 to 20 items.
- Sleep is part of learning.
Why we forget so fast
What you've just learned fades very quickly in the first few days, then more slowly. Psychologist Hermann Ebbinghaus measured this as early as 1885 with his forgetting curve. It's not a flaw in your memory: your brain sorts things and keeps what gets used often. So the goal is to show it that your list gets used often, at the right time.
The 3-step method
1. Test yourself instead of rereading
Hide the answer, try to recall it, then check. This is what researchers call retrieval practice (or the testing effect). In a well-known study, Roediger and Karpicke (2006) showed that students who tested themselves on a text remembered much more of it a week later than those who reread it, even though they spent the same amount of time on it.
In practice: flashcards (I see the word, I look for the translation, I flip) and writing (I type the answer and check the spelling) are two ways of testing yourself.
2. Space out your reviews
Go over the list the next day, then a few days later, then the following week. Each review at the moment you were starting to forget strengthens your memory more than a review done right away. That's spaced repetition.
3. Work with small lists
A 60-word list is discouraging. Three lists of 20 take just a few minutes each to review. Split them by topic (the house, the weather, irregular verbs in -ought…) or by chapter.
An example over one week
You have 20 English words for the test next Friday.
| Day | What you do | Time |
|---|---|---|
| Friday | You create the list, one pass with flashcards | 10 min |
| Saturday | Flashcards, then write out the words you missed | 8 min |
| Monday | Write out the whole list | 8 min |
| Wednesday | Flashcards on the words that are still tricky | 5 min |
| Thursday | One last writing test | 5 min |
Total: less than 40 minutes, spread over a week. That's less than an evening of cramming, and the words stay with you after the test.
The little extras that make a difference
- Say it out loud. With languages, pronouncing the word adds another memory trace.
- Make a sentence. Using the word in a sentence of your own makes it easier to recall.
- Sleep. Sleep helps consolidate what you learned during the day. Reviewing a little in the evening and checking in the morning is very effective.
- Turn off your phone (unless you're studying on it). A short, focused session is better than a long, interrupted one. The Pomodoro technique helps you keep going.
How MemoCard.io applies this method
MemoCard.io was designed around these three habits:
- Test yourself : flashcards to recognize, Learn mode to write and check spelling.
- Space it out : the app schedules your reviews and brings tricky words back more often.
- Break it up : one list per chapter or topic, organized in the app, with your progress list by list.
Try the method with your next list: MemoCard.io is free on iPhone and Android.
Frequently asked questions
How many words can you learn per day?
For vocabulary, 10 to 20 new words a day is a good pace if you also review the old ones. It's better to have fewer words well remembered than lots of words quickly forgotten.
Should I write, or just look at the flashcards?
Both are useful. Flashcards train you to recognize and recall the meaning. Writing checks that you really know the spelling, which matters for a written test.
Does it work for adults?
Yes. The same principles apply at any age, whether you're learning a language, preparing for a competitive exam or memorizing professional vocabulary.
