Cambridge C1 Advanced (CAE) Use of English — the language-in-use half of the Reading and Use of English paper — has four parts and 36 marks. Multiple Choice Cloze, Open Cloze and Word Formation (Parts 1–3) each have eight gaps worth one mark (24 marks). Key Word Transformation (Part 4) has six items worth up to two marks each (12 marks), with partial credit possible. On this hub you work one part at a time with instant scoring; no account required.
Format & timing
The Reading and Use of English paper is one booklet in the real exam; here you train the Use of English half by part. Times below are practice targets, not official invigilated clocks.

On this hub you practise one part at a time. A full paper (Parts 1–4) is roughly 30–40 minutes of focused work — use any tests you choose, not a fixed path.
How it is marked
Parts 1–3 award 1 mark per correct gap (8 gaps each → 24 marks). Part 4 awards up to 2 marks per item (6 items → 12 marks), with partial credit when half the transformation is right. That is 36 marks for Use of English in total. Practice percentages on this hub follow that structure. For overall C1 grades you still need a solid Cambridge English Scale profile (a pass is typically from scale 180+).
How to train Use of English at C1
Precision compounds. Fix patterns before you pile on more random attempts.
- 101
Practise by part first
Use the tabs above to isolate cloze, formation, or KWT until your accuracy stops swinging wildly between attempts.
Open practice grid - 202
Review every wrong answer
Write the pattern, not only the key. Collocation? Function word? Negative prefix? Structure you never use in writing?
- 303
Feed Parts 1 and 4 with vocabulary
Collocations, phrasal verbs, and idioms transfer directly into cloze and transformations. Short daily sets beat rare-word lists.
C1 Vocabulary - 404
Run timed full papers
When ready, do Parts 1–4 in one sitting (~30–40 min). Check the sidebar progress after each run.

Part guides
Frequent mistakes at C1
These cost marks even when candidates “know the word” — train them as targets, not personality flaws.
Part 1
Synonym, not collocation
All four options can “mean” the right thing; only one partners naturally with the surrounding words.
Part 2
Ignoring grammar around the gap
Most answers are function words. Read the whole clause, not the gap alone.
Part 3
Missing negatives or word class
The trap is often un- / in- / dis-, or the wrong part of speech, not a simple suffix change.
Part 4
Breaking the rules of the item
Changing the key word, using more than six words at C1, or keeping the same structure when the stem demands a rewrite.
All parts
Speed without a second pass
C1 rewards precision. A quick skim for agreement, register, and fixed phrases recovers marks you already “knew”.
All parts
Volume without repair
Another random test does less than redoing one weak pattern type (e.g. only open-cloze prepositions).

Strategy before more volume
Part-by-part focus for the paper that rewards precision over rare vocabulary.

Clear answers about format, scoring, timing, and how to practise on this hub.
What is in Cambridge C1 Use of English?
C1 Advanced Use of English has four parts: Multiple Choice Cloze (Part 1), Open Cloze (Part 2), Word Formation (Part 3), and Key Word Transformation (Part 4). Together they total 36 marks and sit inside the Reading and Use of English paper.
How is C1 Use of English marked?
Parts 1–3 give 1 mark per correct gap (8 gaps each → 24 marks). Part 4 gives up to 2 marks per item (6 items → 12 marks), with partial credit when half the transformation is right. Practice percentages on this hub follow that mark scheme.
How long does C1 Use of English practice take?
For practice on this hub, budget about 7–8 minutes per Parts 1–3 task and about 10 minutes for Part 4 — roughly 30–40 minutes for a full Parts 1–4 run if you sit them back to back.
What is the difference between Part 1 and Part 2 at C1?
Part 1 is mostly lexical (collocations, phrasal verbs, near-synonyms with four options). Part 2 is mostly structural: one-word gaps that are usually articles, prepositions, auxiliaries, pronouns, or linkers.
How does Part 4 Key Word Transformation work at C1?
You rewrite a sentence using a fixed key word so the meaning stays the same. Use 3–6 words including the key word, and do not change the key word. Each item is worth up to 2 marks.
How can I improve my C1 Use of English score?
Practise one part at a time, review every wrong answer for the underlying pattern, train collocations and word families, then run timed full papers and retest weak parts.
