C2 Proficiency Speaking Part 3: 10 of the 16 Minutes

The C2 Proficiency Speaking test runs 16 minutes for a pair of candidates.

Part 3 takes ten of them.

That is more than Parts 1 and 2 combined, and inside it the solo turn doubles to two minutes, from the one minute you get at B2 First and C1 Advanced.

SpeakShark is free for building that stamina, three AI conversation sessions a day with no card, each capped at five minutes and four turns.

Key takeaways

Part 3 is ten minutes of a sixteen minute test.
The solo turn is about two minutes, double the level below.
The prompt is a card with a question and some ideas, not photographs.
Cambridge's skills list here includes developing topics, which appears at no lower level.
C2 Proficiency Speaking has three parts, not four.

What Part 3 actually is

Cambridge's description, in full:

The interlocutor gives you a card with a question and some ideas on it and you have to speak for about 2 minutes on your own. After you finish, your partner has to comment and the interlocutor then asks you both a question on the same topic. The interlocutor follows the same procedure with your partner and then leads a discussion with both of you.

And the timing:

10 minutes (2-minute long turn for each candidate and then approximately 6 minutes for the discussion).

That is four distinct stages inside one part, which is why it takes so much of the test.

The ten minute breakdown

Stage	What happens	Roughly
1	You speak alone from the card	2 minutes
2	Your partner comments, then a question to you both	Inside the discussion time
3	The same procedure runs for your partner	2 minutes plus
4	The interlocutor leads a discussion with both of you	Approximately 6 minutes total for the discussion

Set that against the whole test:

Part	What it is	Time
1, Interview	Questions addressed to each candidate in turn	2 minutes
2, Collaborative task	A reaction question on pictures, then a decision task	4 minutes
3, Long turn and discussion	Card, two minute solo turn, then discussion	10 minutes

16 minutes per pair of candidates, or 24 minutes per group of three.

Ten out of sixteen. Whatever else you prepare, this is the part your test is mostly made of.

The card, not a photograph

At B2 First and C1 Advanced the long turn is built on photographs. At C2 it is built on a card with a question and some ideas on it.

That changes the nature of the task.

	B2 First and C1 Advanced	C2 Proficiency
Prompt	Photographs	A card with a question and ideas
Solo turn	1 minute	About 2 minutes
What runs out	Describable content	Nothing visible, so nothing to fall back on

A photograph gives you a floor. Even a candidate with nothing to say can name what is in it and buy fifteen seconds. A card with a question gives you no floor at all: if you have no ideas about the question, there is nothing to describe your way through.

The ideas printed on the card are the support Cambridge provides in place of that floor. They are prompts to develop, not a script to read, and a candidate who works through them as a list will sound like someone reading a list for two minutes.

The C1 Advanced long turn and the B2 First long turn show what the picture-based version asks instead.

Why two minutes is a different task

One minute of solo speech is a paragraph. Two minutes is a structure.

At one minute, a candidate can hold one idea in mind, deliver it, and finish. At two minutes that approach runs out at around the halfway mark, and the second half is where most people either repeat themselves or stop.

What actually fills two minutes is development: taking a point and moving it somewhere. A reason, then a consequence, then an exception, then a case where it does not hold. Each move buys time and each one is a language demand rather than a memory demand.

The Council of Europe describes a C2 user as someone who can summarise information from different sources, "reconstructing arguments and accounts in a coherent presentation", and who "can express him/herself spontaneously, very fluently and precisely, differentiating finer shades of meaning even in more complex situations". Reconstructing an argument coherently is not something one minute has room to show. Two minutes does, and that is what the extra minute is for. CEFR levels explained for speaking covers the ladder underneath it.

Developing topics, the phrase that only appears here

Cambridge's skills list for Part 3:

Speaking on your own for a longer time, expressing and justifying opinions, developing topics.

We checked the equivalent lists one and two levels down. Developing topics is not on either of them. At C1 Advanced the long turn asks for comparing, describing, expressing opinions and speculating. At B2 First it asks for comparing, describing and expressing opinions.

So the C2 long turn is not the C1 long turn held for longer. It swaps the visual skills out and puts development in, which is a different kind of work: less about what you notice and more about where you take it.

The practical drill follows directly:

Take one question. Any question with an arguable answer.
Answer it in a sentence. That is your position.
Give a reason, then a consequence of that reason.
Name the exception, the case where your position weakens.
Come back to the position, adjusted.
Time it. Aim for two minutes with no gap.

Repeat daily on different questions and the moves become automatic. Twelve daily speaking drills from B1 to C1 builds the underlying habit, and a free daily session is enough volume to keep it running.

The four stage sequence

Part 3 does not end when your two minutes do, and this catches people.

After your long turn, your partner comments. Then the interlocutor asks you both a question on the same topic. Then the whole procedure runs again for your partner, with you commenting on theirs. Then the interlocutor leads a discussion with both of you.

So you are on task for the full ten minutes, not for two. Three of the four stages involve reacting to somebody else, which is the same demand Part 2, the collaborative task is built on, and it is the demand no worksheet can rehearse.

Two things follow for practice. Listen during your partner's turn, because you have to comment on it. And get comfortable being brief: a comment is not a second long turn, and running long into the interlocutor's next question is worse than stopping early.

Role play scenarios for speaking practice and finding an online speaking partner are the two realistic routes to practising against a response. A 30 day plan to improve speaking and speaking exercises for adult learners fit the habit around work, and if clarity slips when you are concentrating on structure, how to improve English pronunciation targets that directly. If it is nerves rather than language, why your English speaking is not improving and online methods to build confidence in English are the better reading.

Cambridge lists C2 Proficiency at CEFR level C2 with a scale score of 200 to 230, four papers and an exam length of about four hours. Coming up from the level below, the C1 Advanced Speaking format and B2 First versus C1 Advanced speaking show how much the structure changes on the way here.

Two details about the room, both from Cambridge: there are two examiners, one who talks to you and one who listens, and one of them could be examining remotely. Examiners may also enter marks using a mobile phone app.

What we could not verify

We have not reproduced the assessment criteria. Cambridge publishes its own scales and we are not paraphrasing band descriptors.

We could not find a published split of the six discussion minutes across the stages inside Part 3. Cambridge gives the total and the two minute long turns, and we have not gone beyond that.

We could not find published group-of-three per-part timings, only the 24 minute total.

We have not published sample cards. Cambridge publishes a sample test, and that is the right source for real task material.

We are not stating pass rates or average scores by part. We found no attributable figure.

How we researched this guide

The Part 3 description, the ten minute timing and its breakdown, the three part structure, the other two parts, the 16 and 24 minute totals, the two examiner setup, the remote examiner note and the marking app detail come from Cambridge English's C2 Proficiency exam format page. The CEFR level, the 200 to 230 scale score, the four papers and the four hour exam length come from the C2 Proficiency qualification page. Both were read directly in a browser.

The comparison of skills lists comes from reading the C1 Advanced and B2 First format pages the same way and checking them field by field. "Developing topics" appearing at C2 and at neither level below is the kind of detail that only survives a direct comparison, and it disappears the moment any of the three lists is summarised as "talking on your own".

The observation that Part 3 is ten of sixteen minutes is arithmetic on Cambridge's own published timings, not a claim we found elsewhere.

The C2 descriptor comes from the Council of Europe's global scale, Table 1, read on the page rather than quoted from memory. That check mattered: the phrase we first reached for, about presenting an argument with an effective logical structure, is not on the global scale at all. It belongs to a different CEFR table, and the wording that is on Table 1, about reconstructing arguments in a coherent presentation, turned out to fit the two minute turn better anyway.

Practise speaking, from SpeakShark

SpeakShark is an AI English speaking practice app, and it is our pick for Part 3 because ten of the sixteen minutes here are spent either speaking at length or reacting to another person. Both need volume rather than reading. You talk, the AI answers what you actually said, and you get speaking feedback while the conversation is still going. The free tier gives basic feedback; the detailed pronunciation and grammar breakdown is on Premium.

Being straight about the limits: a free session runs five minutes with four turns, which suits daily practice of the development drill rather than simulating a full 16 minute paired exam.

Start free with three sessions a day and no card. Paid sessions run ten minutes with unlimited turns. Limits are on the pricing page, and how it works walks through a full session.

We are a speaking improvement tool. We are not an exam preparation provider, and we are not affiliated with Cambridge English, the IELTS partners, Pearson or any exam board. For test format, booking and official practice material, go to the exam body directly. Use SpeakShark to make your spoken English stronger, and use official material to learn the test.

FAQ

What is C2 Proficiency Speaking Part 3?

It is the long turn and discussion. Cambridge says the interlocutor gives you a card with a question and some ideas on it and you speak for about two minutes on your own. Your partner then comments, the interlocutor asks you both a question on the same topic, the same procedure runs for your partner, and the interlocutor then leads a discussion with both of you.

How long is C2 Proficiency Speaking Part 3?

Ten minutes. Cambridge breaks that down as a two minute long turn for each candidate followed by approximately six minutes of discussion. The whole Speaking test runs 16 minutes per pair of candidates, so Part 3 alone is more than half the test and longer than Parts 1 and 2 put together.

How long do I speak on my own at C2 Proficiency?

About two minutes. That is double the solo turn at B2 First and C1 Advanced, where Cambridge gives one minute per candidate. It is also driven by a card with a question and some ideas rather than by photographs, so the material you build the two minutes from is written prompts rather than images.

What is on the card in C2 Proficiency Part 3?

Cambridge describes it as a card with a question and some ideas on it. The question is the task and the ideas are support, which means the card gives you a starting structure rather than a picture to interpret. That is a different kind of prompt from the photographs used in the long turns at B2 First and C1 Advanced.

What does Cambridge say to practise for Part 3?

Speaking on your own for a longer time, expressing and justifying opinions, and developing topics. Developing topics is the phrase worth noticing. It is not on the skills list for the equivalent parts at B2 First or C1 Advanced, and it describes what two minutes of solo speech actually requires: taking a point somewhere rather than restating it.

How do I practise a two minute solo turn?

Against a clock, out loud, on prompts you have not seen. Two minutes is long enough that structure matters more than vocabulary, so practise taking one idea and developing it rather than listing several. Recording yourself and checking where you stalled is more useful than reading model answers, because the failure is almost always pacing rather than language.
