UK SELT SimulatorCommon mistakes in the B1 speaking test conversation
Published 2 October 2026
If you are preparing for the B1 English test for settlement or citizenship, you have probably read that it is a "conversation." That is true, but it is a conversation with a fixed structure and set marking criteria behind it. Most of what costs people marks is not bad English. It is misunderstanding what the conversation is actually testing.
This article goes through the mistakes that come up again and again in the two approved B1 tests — Trinity GESE Grade 5 and LanguageCert ESOL SELT B1 — and ties each one to what the official marking criteria actually assess. No scare stories. Just what the examiner is listening for, and what trips people up.
GESE Grade 5: the exam is two conversations, not one
GESE Grade 5 lasts 10 minutes in total, split into two phases: the Topic phase (up to 5 minutes) and the Conversation (up to 5 minutes). Both are assessed separately. Here is where people lose marks in each.
Mistake: answering instead of talking
In the Topic phase, the examiner asks about points from the topic form you prepared and brought with you. The exam expects you to give linked long turns — connected speech that develops a point — not short factual answers. Candidates who answer in single sentences and then stop, waiting for the next question, are not doing what this phase asks for.
The Conversation phase has the same trap in a different shape. The examiner picks two subject areas from a fixed pool and has a genuine two-way exchange of information, ideas and opinions with you — it is explicitly not meant to be a Q&A interview. Treating it like an interview, where you wait to be asked something and give the shortest honest answer, undersells what you can do.
Mistake: forgetting to ask a question back
In both phases, you are expected to ask the examiner at least one question — one about the topic area during the Topic phase, and one about a subject area during the Conversation. This is easy to forget when you are focused on answering well. Plan for it: if you are talking about your job, you can ask the examiner something as simple as "What about you — do you enjoy your work?"
Mistake: reciting the topic form
The topic form is meant to guide a spontaneous discussion, not to be memorised and delivered as a script. Recitation is specifically penalised. If you have not seen our full guide to building a safe topic form, read it here before you write yours.
What actually fails the exam
It is worth knowing this clearly, because people worry about the wrong thing: at Grade 5, you fail only if both phases are graded D, or if you turn up without a topic form (an automatic fail, regardless of how well you speak). One shaky phase does not sink you on its own. Forgetting the form does.
LanguageCert SELT B1: the conversation is spread across four parts
LanguageCert SELT B1 runs 11 to 13 minutes in total (around 12 minutes), across four parts that always run in the same order. The conversational demands are different in each one.
Mistake: going silent when you have to start
Part 2 has two short role-plays. In the first, the examiner starts. In the second, you are given the situation and then told "You start." Freezing here is common, but the silence is deliberate — it is testing whether you can initiate, not just respond. We cover this in detail in a dedicated article, but the short version: prepare a simple, relevant opening line and say it without waiting to be prompted again.
Mistake: only answering in the decision task
Part 3 gives you and the examiner a shared picture sheet — for example, gift options with prices — and a goal to reach together, such as choosing a wedding present. This is built to be two-way: you must ask questions as well as answer them, and work with the examiner toward an agreement. Candidates who only respond to the examiner's questions, without asking anything themselves, are not using the structure the task is built around.
Mistake: rushing the decision, or never making one
The marking rewards the quality of the exchange more than whether you land on an agreement — but the task is still meant to move toward a decision. Agreeing to the first option offered just to end the task, or refusing to settle on anything after going back and forth, both waste the chance to show real negotiation language: expressing a preference, giving a reason for it, responding to a counter-suggestion.
Mistake: a short answer where a long turn is expected
Part 4B asks you to prepare for 30 seconds with notes, then speak alone for up to 1.5 minutes on a topic linked to what you just heard in the listening passage. Thirty seconds of notes is enough to sketch two or three points to develop — skipping that preparation and speaking from nothing is a common reason candidates run out of things to say well before the 1.5 minutes is up.
Two mistakes that apply to both exams
Over-using "can you repeat that?"
Asking the examiner to repeat or rephrase is a normal, expected behaviour in both exams — it will not cost you marks by itself. What the criteria describe as a concern is needing it repeatedly through the exam, which reads as difficulty following the conversation rather than a single moment of not catching a word.
Giving facts without reasons
Both exams credit you for explaining why, not just stating what. GESE Grade 5 explicitly assesses your ability to give reasons for statements and respond to requests for clarification. LanguageCert's Part 1 personal questions are frequently followed by a "Why?" prompt. A fact on its own is a weaker answer than the same fact with a reason attached.
What this is not about
None of this is about your accent, and none of it is about sounding like a native speaker. We cover that separately in a dedicated article — the short answer is that accent is not one of the things either exam marks you on.
Whether the B1 test is the right one for your specific application, and which providers are currently approved, is set by the Home Office. Check the current requirements at gov.uk before you book.
Practise the real thing
UK SELT Simulator runs spoken mock sessions in both formats — GESE Grade 5 (Topic phase, then Conversation) and LanguageCert SELT B1 (all four parts, in order) — with an AI examiner and a short report after each session, so you can see these habits in your own speech before exam day.
