B1 English Flashcards: How to Study B1 Vocabulary
On this page
B1 English flashcards work best when they follow three rules: build them around real topics, review them on a spaced schedule, and add new cards at a pace you can keep for months.
At B1 you already know the basics. The new words are less "table" and "chair" and more "improve", "advantage" and "unfortunately" — words for explaining, comparing and giving opinions. That kind of vocabulary needs a slightly different way of studying.
This guide is the practical companion to what B1 English level means. That post explains what you can do at B1. This one shows how to build the vocabulary, card by card.
TL;DR:
- There is no official B1 word count. About 2,000 words is a common planning figure, roughly 1,000 more than A2.
- On 15 minutes a day, add about 5-10 new cards and clear your reviews first.
- A good B1 card has a short English definition and a full example sentence, not just a translation.
- Study by topic (travel, work, money) so new words connect to each other.
- Check your progress with a level test every 4-6 weeks, not by counting cards.
How many B1 English flashcards do you need?
The CEFR describes what learners can do at each level. It does not give an official number of words.
So any word count is a planning estimate, not an exam rule. A widely used rough guide puts A2 at about 1,000 words and B1 at about 2,000 — see how many English words you need for the full table.
If you already have most of A2, that means roughly 1,000 new cards:
| New cards per day | Time to add ~1,000 cards |
|---|---|
| 5 | about 7 months |
| 8 | about 4 months |
| 10 | about 3 months |
Faster looks better on paper, but every new card comes back as a review. Add more than your daily time can absorb and the review pile grows every day. How many new words to learn per day walks through that math.
What makes a good B1 flashcard?
At A1-A2, a picture or a translation is often enough. B1 words are more abstract, so a bare translation is easy to forget.
Give every card three parts:
- A short definition in simple English. One line you could say out loud.
- A full example sentence. It shows the grammar around the word: the preposition after it, whether it is a verb or a noun, how formal it is.
- A blank to fill. Show the sentence with the word missing. Having to recall the word, not just recognise it, is the point of active recall.
Budling's official sets use this format: every card has a definition and an example sentence with the target word blanked out. You can see it in any set in the B1 flashcards library.
How should you review B1 flashcards?
Spread your reviews out instead of cramming. A large review of research on verbal learning found that spacing study sessions apart gives better long-term recall than the same amount of study in one block (Cepeda et al., 2006, Psychological Bulletin).
A flashcard app does the spacing for you by showing each card again just before you are likely to forget it. Spaced repetition explained covers how that works.
Three habits keep it working:
- Reviews first. Clear today's due cards before you add new ones.
- Rate honestly. "Good" means you remembered without a long pause.
- Fix stubborn cards. If a card keeps coming back as "Again", rewrite its example sentence. The sentence is usually the problem, not you.
A 4-week B1 flashcard study plan
You need about 15 minutes a day. Keep new cards at 5-10 a day throughout.
| Week | Focus | Where to start |
|---|---|---|
| 1 | Everyday situations | Travel and work sets |
| 2 | Experiences and opinions | Pair new words with the present perfect and future time clauses |
| 3 | Money and services | Money & finance sets: banking, shopping, bills |
| 4 | Review only | No new topic. Mix your sets and write three sentences for your 10 hardest cards |
After week 4, take the free English level test to see whether your estimate has moved.
Which B1 topics should you learn first?
Start with the topics you actually meet.
- Moving abroad for work? Work and money vocabulary first.
- Travelling? Transport, hotels and food.
- Taking an exam? Cambridge's B1 Preliminary is targeted at B1, and scores of 140-159 are reported as B1 (Cambridge English results page). Everyday topics like travel, work, health and education are a safe default.
Are flashcards enough to reach B1?
No. Flashcards build your memory for individual words. B1 also needs listening, reading longer texts and making your own sentences.
Use flashcards for the vocabulary part. Then meet the same words again in short articles, and write a few sentences of your own each day.
A simple test: can you use the word in a sentence you made up yourself? If yes, it has moved from your flashcards into your English.
What comes after B1?
When your B1 sets feel comfortable, move on to the B2 vocabulary hub. Until then, 15 steady minutes a day in the B1 flashcards will do more than a weekend of cramming.
