B1 Preliminary Speaking Part 2: the collaborative task

B1Listening & Speaking40 questionsUpdated

In the B1 Preliminary collaborative task you and your partner look at a set of pictures and discuss a situation together — what to buy someone, how to spend a free day, which activity a group should choose. You are marked on the conversation, not on winning it, so the candidate who asks questions and reacts scores better than the one who delivers a monologue.

What this task tests

  • Whether you can make a suggestion and give a reason for it.
  • Whether you react to your partner’s ideas rather than waiting for your turn.
  • Agreeing and disagreeing politely: ‘That’s true, but…’, ‘I’m not sure about that.’
  • Asking your partner for their opinion: ‘What do you think?’, ‘How about you?’
  • Covering several of the options rather than fixating on one.
  • Reaching a decision, or agreeing to differ, before the time ends.
  • Keeping the conversation going when your partner gives short answers.
  • Turn-taking: coming in without interrupting and without disappearing.
  • Using fillers and repair phrases instead of falling silent.

How to do it

  1. Step 1:

    Start with one option, not a plan

    ‘Shall we start with the concert tickets?’ opens the task in four seconds. Trying to organise the whole discussion first wastes the opening and often confuses your partner.

  2. Step 2:

    Suggest, then justify, then ask

    Three moves every time: ‘I think a book would be good, because she reads a lot. What do you think?’ That pattern alone can carry most of the task.

  3. Step 3:

    React before you add

    ‘That’s a good idea’ or ‘Oh, I hadn’t thought of that’ costs two seconds and is marked as interactive communication. Adding your own idea on top of an unacknowledged one is not.

  4. Step 4:

    Disagree politely, with a reason

    ‘I’m not sure about that, because it might be too expensive.’ Polite disagreement produces more conversation than agreement does, and shows more language.

  5. Step 5:

    Rescue a quiet partner

    Ask a direct question: ‘Which one would you choose?’ You are assessed on your own performance, and drawing your partner in is part of it.

  6. Step 6:

    Move on once an option is done

    Two or three exchanges per picture is enough. ‘Shall we look at the other one?’ keeps you covering the material rather than exhausting it.

  7. Step 7:

    Watch for the decision

    When the examiner reminds you of the time, start closing: ‘So shall we agree on the trip, then?’ A task with no decision at the end feels unfinished.

  8. Step 8:

    Keep speaking through the gaps

    ‘Let me think…’, ‘How can I say it…’, ‘The thing is…’ hold the turn while you find the words. Silence hands the turn away and loses fluency marks.

Mistakes that cost marks

  • Not thisI spoke for ninety seconds without stopping so I would have enough to say.

    ThisI spoke for twenty seconds and then asked my partner what they thought.

    Interactive communication is a marked criterion. A monologue in a paired task scores below a shorter, genuine exchange.

  • Not thisI disagree. That is a bad idea.

    ThisI’m not sure about that — it might be quite expensive.

    Blunt disagreement closes the conversation. Softened disagreement with a reason opens it and shows more language.

  • Not thisI waited for my partner to start every time.

    ThisI opened two of the options myself.

    You are assessed individually, so a candidate who never initiates cannot show the range the task is designed to elicit.

  • Not thisWe talked about the first picture for the whole three minutes.

    ThisWe spent about forty seconds on each and reached a decision.

    Covering several options gives you more vocabulary and more chances to agree and disagree.

  • Not thisWhat you think about this one?

    ThisWhat do you think about this one?

    The auxiliary is needed in the question. This form is used repeatedly in the task, so the error repeats too.

  • Not this(long silence while thinking of a word)

    ThisLet me think… how can I say this…

    Fillers keep the turn and are natural English; silence is scored as hesitation.

Frequently asked questions

What if my partner is much weaker than me?

Help them: ask short direct questions and give them easy things to react to. You are marked on your own performance, and drawing someone in is exactly the interactive skill being assessed.

What if my partner talks too much?

Come in politely at a natural pause — ‘Can I just say something about the second one?’ Examiners are used to it, and a candidate who never gets a turn cannot be assessed.

Do we have to agree at the end?

You have to reach a conclusion, which can be agreeing to differ. ‘We can’t agree — I still prefer the trip and you prefer the meal’ is a perfectly good ending.

Can I prepare phrases in advance?

Yes, and you should. Ten phrases — two for suggesting, two for agreeing, two for disagreeing, two for asking, two for closing — will carry the whole task.

Does it matter if I make grammar mistakes?

Much less than stopping. Communication and interaction are separate criteria from accuracy, and a fluent exchange with small errors scores well.
