How Our CEFR Levels Are Set
A test result is only useful if you know how it was made. This page explains, in plain words, how every Cubbbix language test is built, how the score becomes a CEFR level, what the test measures, and what it does not. Nothing here is hidden.
The test format
The same format for every language, every time.
- Every test has 40 questions, drawn from that language's question bank as a fixed mix: 14 Beginner, 14 Intermediate and 12 Advanced, shuffled within each band.
- The mix is the same for every attempt. The difficulty does not change based on your answers.
- Every question has 4 options and one correct answer, a difficulty level, and a category: grammar, vocabulary, verbs or reading.
- Every question is timed at 12 seconds. A full test takes at most 8 minutes.
- The test and your result are free. There is no signup.
How the score becomes a CEFR level
Your score is the number of correct answers out of 40.
| Score out of 40 | CEFR level | What it means |
|---|---|---|
| 0 – 6 | A1 — Beginner | You can understand and use familiar everyday expressions and very basic phrases. |
| 7 – 13 | A2 — Elementary | You can understand sentences and frequently used expressions about the things that matter most day to day. |
| 14 – 18 | B1 — Intermediate | You can deal with most situations likely to come up while travelling, and communicate everyday ideas with reasonable accuracy. |
| 19 – 22 | B2 — Upper Intermediate | You can interact with fluency and spontaneity, in university and professional settings. |
| 23 – 25 | C1 — Advanced | You can express yourself fluently and spontaneously, in demanding academic and professional settings. |
| 26 – 40 | C2 — Proficient | You can understand with ease almost everything you hear or read, and express yourself very fluently and precisely. |
The bands are fixed. The same score always gives the same level, in every language.
What your result shows
More than a level: where to improve next.
When you finish, you see your score out of 40, your CEFR level, and your weakest skill. The weakest skill is worked out from your percentage in each area — grammar, vocabulary, verbs and reading — so you can see what to practise first.
How the questions are checked
One check across every question bank.
On 8 November 2026 we checked 2,355 questions across all 18 question banks and amended 190 of them. All 18 banks passed the check. Every question in a bank carries one correct answer, a difficulty level and a category.
What the test does not do
The limits matter as much as the result.
- It does not test listening. There is no audio in the test.
- It does not test speaking or writing.
- It tests grammar, vocabulary and reading only.
- The anti-cheat is browser-level only: copy, paste and the right-click menu are switched off while you take the test.
- The result is an estimate. The result screen says it plainly: “An estimated practice result from Cubbbix — not an official IELTS/Cambridge result.”
Validation status
Stated plainly, not hidden.
The CEFR mapping on this page is Cubbbix’s own. It is based on the CEFR descriptors and on our internal question audit. No external body has independently validated it. We say this here because a level you trust should come with its limits stated, not hidden.
The certificate
Optional, and verifiable.
After your result you can buy an optional certificate for $9.99. Anyone can verify it with the QR code or on the verify page, which shows the name, language, CEFR level and verification ID recorded for that certificate. It is a verifiable record of your Cubbbix result, NOT an official exam certificate. Admission, immigration and employment decisions may still require a proctored exam from another provider.
