Short answer: you forget because you don't get the chance to remember. Spaced repetition means revisiting a topic just as you're about to forget it, again and again, at growing gaps. Flashcards make it easy: look at the question, try to answer from memory, then check. Done for a few minutes a day, it beats a long cram night.
Why we forget
Memory fades fast after we first learn something, unless we use it again. This is known as the forgetting curve. Each time you successfully recall something, the memory lasts longer before it fades. The trick is to recall it at the right time: not the same hour, when it's too easy, and not after a month, when it's gone.
Two ideas worth knowing
- Active recall (the testing effect): trying to remember an answer teaches you more than reading it again.
- Spacing: practising on several days beats the same total time in one sitting.
A schedule you can copy
When you learn something new, review it:
- The next day.
- 3 days later.
- A week later.
- Two or three weeks later, before the exam.
If you get a card wrong, it goes back to the start. If you get it right, it moves to the next gap. That's the whole method.
How to make good flashcards
- One idea per card. If a card needs a paragraph, split it.
- Ask a question on the front, not a heading. 'Why does the moon have phases?' beats 'Moon phases'.
- Use your own words, and your own language.
- Add a quick diagram where it helps.
- Make cards from the textbook pages you just studied, so they match the exam.
A 5-minute daily habit
- Open today's cards. Answer each one out loud or in your head before flipping.
- Mark the ones you got wrong. They will come back sooner.
- End with a 60-second speed round, the fast kind, where you answer as many as you can.
- Look at your mistakes list once, then stop.
Where Gyanmor helps
Gyanmor's Practice screen has flashcards that come back when it's the right time to remember them, and a 60-second speed round where 5 in a row gives double points. Wrong answers from tests wait in Mistakes to fix, so the hard ones keep coming back until they stick. Streaks and XP reward showing up, which is the hardest part.
You don't need an app to do spaced repetition. A box of paper cards and a calendar work. But if the app does the scheduling, you can spend your five minutes remembering, not planning.
Questions
What is spaced repetition?
It is a study method where you review a topic at growing intervals, for example after 1 day, 3 days, a week and a few weeks, so you recall it just before you would forget it.
Do flashcards really work for school exams?
They work well when you try to answer from memory before you flip the card, when each card holds one idea, and when you review them across several days rather than once.
How long should I study with flashcards each day?
Five to fifteen minutes a day is enough for most students. Short and regular is better than long and rare.
Does Gyanmor have flashcards?
Yes. The Practice screen has flashcards that come back when it's the right time to remember them, plus a 60-second speed round and a list of mistakes to fix.
