✅ The Cambridge certificate never expires. Unlike IELTS and TOEFL (valid for only 2 years), Cambridge English Qualifications are valid for life. You prepare the exam once and the certificate serves you forever — for university, immigration or work.
B2 First and C1 Advanced share the same four-paper structure (the table shows C1 Advanced; B2 First is equivalent, slightly shorter):
| Paper | Time | Parts | Content |
|---|
| Reading and Use of English | 1h30 | 8 | cloze, word formation, key word transformations + reading |
| Writing | 1h30 | 2 | compulsory essay + 1 task of your choice (letter, report, review, proposal) |
| Listening | ~40 min | 4 | audio: multiple choice, sentence completion, multiple matching |
| Speaking | ~15 min | 4 | face to face with an examiner and, usually, another candidate |
The most feared paper is usually Use of English: you don't pass it by reading more, you pass it by drilling the four task types until they're automatic. That's exactly what the bot gives you in daily doses.
The Cambridge English Scale — what level each grade gives
All results are reported on the Cambridge English Scale (80–230). The exam you sit and the score you get determine the CEFR level you are certified at:
- B2 First — Grade A (180–190) → certifies C1. Grade B/C (160–179) → certifies B2. 140–159 → certifies B1.
- C1 Advanced — Grade A (200–210) → certifies C2. Grade B/C (180–199) → certifies C1. 160–179 → certifies B2.
Important detail: if you sit C1 Advanced and your real level is B2, you still receive a certificate (at B2 level). The exam is not a binary pass/fail: it certifies the level you demonstrate.
Use of English — the part that makes the difference
This is where many candidates' grade is decided. It measures real language control, not memory. Four task types:
- Multiple-choice cloze — pick the correct word from 4 options for each gap. Tests collocations and vocabulary nuance.
- Open cloze — fill the gap with no options. Tests grammar and function words (prepositions, articles, connectors).
- Word formation — transform a root word so it fits (e.g. able → unable, strong → strength).
- Key word transformations — rewrite a sentence keeping the meaning and using a compulsory word.
The bot practices multiple-choice cloze and word formation with instant correction: you see right away why one option is correct and the others are not.
Writing and Speaking — AI feedback, not generic
Cambridge scores Writing with four official criteria — Content, Communicative Achievement, Organisation and Language — and Speaking with Grammar & Vocabulary, Discourse Management, Pronunciation and Interactive Communication.
The bot calibrates its AI to those criteria. You send your text or your voice message and get:
- An indicative level (B1 / B2 / C1) on the Cambridge scale.
- Concrete corrections: what fails, where, and how to fix it.
- Vocabulary and structure suggestions to move up a band.
