Paper 1

Reading & Use of English.

Seven part types at both levels, built to the official format — and unlike the real paper, every single question ends in an explanation.

Try a free B2 exercise C1 Advanced exercises

01You sit the paper as it really looks. The official rubric, the real number of questions, a running clock. Multiple-choice cloze at B2 — pick the word that fits the gap.

02C1 open cloze — no options to lean on. At C1 Advanced you type the missing word yourself. The engine accepts every answer Cambridge would.

03Your score, the moment you finish. Six out of eight and a word of encouragement — then straight down into what the two mistakes can teach you.

04Instant score, wherever you are. Finish and the result is on screen immediately — the whole paper works on a phone as comfortably as on a laptop.

05The part that actually teaches. Every question comes back marked: what you chose, what was right, and the line of the text that proves it. This is where the learning happens.

Paper 2

Writing.

You write against real Cambridge briefs — essays, emails, reports, proposals, reviews — and Felix, our examiner, marks every submission on the four official scales.

Try a writing task How the marking works

01A real brief, a clean page. The task, the word target and a suggested clock — nothing else between you and the writing.

02Marked on the official Cambridge scales. Content, Communicative Achievement, Organisation, Language — each 0–5, with an estimated level, in about half a minute.

03Your own words, marked line by line. Slips in red with the correction, stronger wording in amber, the phrases you nailed in green — every mark numbered and explained.

04An examiner's comment — and a plan. A short verdict in plain English, what you did well, and the two or three things that would lift your band next time.

05A model answer, with phrases worth stealing. Every free task ships a model text with its best phrases highlighted — ready to reuse in your own writing on exam day.

06Proof you're improving. Edit, resubmit, and the banner shows exactly how far you've come — 13 to 16 out of 20 in one rewrite.

07Write anywhere. The same editor, brief and marking on your phone — a report on the tram counts just as much.

Paper 3

Listening.

Studio-recorded tasks in the official format — everything is played twice within one recording, exactly like the real exam.

Try a free listening task C1 Advanced listening

01Press play once, follow the narrator. Five speakers, eight options, the real pacing — the recording carries you through both listenings by itself.

02The hardest part, done properly. C1 multiple matching runs two tasks at once with three extra options in each — the exact shape that costs the most marks on exam day.

03Score first, understanding second. The instant result is just the start — every question is explained, so you know why the tempting option was wrong.

04Green, red — and the why. Every option is marked and every question explained, so the tempting wrong answer never fools you twice.

05Sentence completion in your pocket. Type what you hear, on any device — the audio player and answers work the same on a phone.

Paper 4

Speaking.

The paper nobody else lets you practise alone. Speak and your words are transcribed live — no microphone? Type instead. Every part ends with Felix's marking.

Try a free speaking drill How speaking is marked

01The examiner asks, you answer. Part 4 discussion questions at C1 — answer out loud against the clock, or type your turns. Sign in and a live AI examiner asks follow-ups.

02The real task, the real mind map. Part 3 hands you the exam's spider diagram and two minutes to discuss — then a decision question, just like the real room.

03Felix marks what you said. Question by question: the exact words to fix, a stronger version of each, and an indicative band — Grammar & Vocabulary, Discourse Management, Interactive Communication.

04Say it better. Your own sentences, upgraded — the exact stronger version of what you said, ready to reuse on exam day.

05The photo long turn, timed. Compare the photos for one minute against the ring clock — on your phone, with the phrase bank one tap away.

Everything you just saw is included.

Over a thousand exercises across both levels, instant marking with an explanation for every question, and Felix’s feedback on your writing and speaking — from the first free exercise to the full mock exams.
