Spaced Repetition
Spaced Repetition for IELTS Vocabulary
Spaced repetition is a simple idea: review a word when you are close to forgetting it, not every time you open your notebook. For IELTS vocabulary, that means fewer giant cram sessions and more short reviews that keep useful words available for reading, listening, speaking, and writing.
Why is spaced repetition useful for IELTS vocabulary?
Spaced repetition is useful for IELTS vocabulary because it schedules reviews around memory, not around the page number in a notebook. A learner first reviews words that are due today, then grades recall honestly: Hard when the word arrived late, Good when the meaning was clear, and Easy when the word could be used quickly in a natural phrase. SM-2 style review makes strong cards wait longer and brings weak cards back sooner, so study time goes toward the words most likely to disappear. For IELTS, that matters because vocabulary has to survive several contexts: recognizing words in reading, hearing them in listening, and producing them in speaking or writing. Cramming can help a word feel familiar for one evening, but spaced review is the steadier system for long-term recall before the next practice test.
The three-grade rule
You do not need ten buttons to review a vocabulary card. Most learners can grade recall with three honest choices:
Hard
You recognized the word late, guessed, or needed the example. Bring it back soon.
Good
You remembered the meaning and could understand a sentence. Let it wait longer.
Easy
You knew it quickly and could use it. Push it farther into the future.
How to grade IELTS vocabulary honestly
The best grade is the one that tells the truth about recall. Do not mark a card "Easy" because the word looks familiar. Ask whether you could understand it in a passage or use it in a sentence without pausing.
- Mark Hard if you remembered only after seeing the first letter or example.
- Mark Good if you knew the meaning but the example sentence still felt useful.
- Mark Easy only when the meaning and one natural phrase came quickly.
- Rewrite the card if you miss it three times for the same reason.
Do not add too many new words
The common mistake is adding 80 new words on Sunday and then drowning in reviews by Wednesday. For IELTS, a better default is 3-8 new cards per day while keeping your due cards manageable. If tomorrow's queue already looks heavy, review only and add nothing.
A simple review rhythm
| Session | What to do | Stop when |
|---|---|---|
| Morning | Review due hard cards | 10 cards or 5 minutes |
| Afternoon | Add words from reading or class notes | 3-8 useful cards |
| Evening | Review today's due queue | The queue is clear |
FAQ
How often should I review IELTS vocabulary?
Review IELTS vocabulary every day when possible, but keep the session small: clear due cards first, add new cards only if tomorrow's queue is manageable, and stop before review becomes a punishment.
What should I do when a word keeps coming back as hard?
Rewrite the card. Add a clearer example, one collocation, or a contrast with a confusing word. Repeated Hard grades usually mean the card is vague, overloaded, or disconnected from real IELTS use.
Is SM-2 better than cramming for IELTS vocabulary?
For long-term recall, SM-2 style spaced repetition is usually better than cramming because it schedules reviews after successful recall and brings weak cards back sooner. Cramming can still help before a test, but it should not be the main vocabulary system.
How Banded supports this
Banded uses an honest SM-2 style review flow with Hard, Good, and Easy grading. The app is intentionally small: open the due queue, flip the card, grade recall, and leave. That shape matters because vocabulary study works best when the review habit survives normal days.
