One card, one idea
The rule worth remembering: each card asks one thing. If the back has three meanings, two synonyms and four usages, you will not know which part you actually remembered when you rate it. Split a crowded card into several.
For words with many meanings, pick the one that shows up in the topic you are practising (Education, Environment, Technology and so on) and leave the others for later.
What a good card contains
You do not need fancy cards. A simple structure is enough:
- Front: the word or phrase, or a sentence with a gap to fill in.
- Back: a short meaning, either in your own language or a simple English definition.
- One example sentence, written by you or copied from a reliable source, ideally close to an IELTS topic.
- The pronunciation or a note about it, so you do not have to look it up again.
- A common collocation if there is one, such as "make a decision".
A 4-step plan with tasks and a roadmap
Fibonacci Review keeps flashcards, tasks and learning roadmaps in one app, so you can split the work like this.
Step 1, plan the roadmap: create a roadmap called "IELTS vocabulary" and break it into milestones by topic, one topic per step. Step 2, build cards: one deck per topic, around 5 to 10 new cards a day. Step 3, review daily: open the flashcards, answer before you flip, then rate Again, Hard, Good or Easy. Step 4, use the words: create a task such as "write 3 sentences with this topic's new words" and let it repeat on the default Fibonacci schedule.
Step 4 matters because recognising a word when you read is different from being able to use it when you write or speak. Flashcards help you remember; the task makes you use the words.
Limits and keeping a steady pace
The free version allows up to 3 decks of 30 cards each, so roughly 90 cards. If you need more, you can merge topics or use Premium to remove the limits. Premium also adds a type-the-answer mode, which is handy for practising spelling.
Consistency matters more than capacity. Ten minutes a day is usually easier to sustain than two hours at the weekend. Set a reminder so reviewing becomes a habit.
If you are on Android, try building your first few IELTS cards in Fibonacci Review. The free version on Google Play is enough for a small roadmap, and you do not need an account to start. The app is Android-only.
