Why did I get C+ in OET Speaking? The five usual reasons and how to fix them

Scripting whole paragraphs in the three minutes of preparation time is the most common C+ pattern. The candidate delivers the planned explanation regardless of what the patient actually says, so the recording shows a monologue rather than an exchange. This costs heavily on structure and relationship building, even when the language itself is fluent and accurate.

The fix: use preparation time on the task list and your opening line, not on full sentences. Plan what you need to cover, then let the patient's actual responses decide your next sentence.

Clinical communication scoring rewards eliciting the patient's own understanding and concerns before you explain anything. Candidates who move straight to delivering information score low on information gathering and understanding the patient's perspective, even if the information itself is correct and clearly delivered.

The fix: open with a question, not a statement. Ask what the patient already understands or is most worried about, and let the answer shape what you explain first.

Clinical terminology aimed at a patient or carer, rather than plain language, lowers appropriateness of language and intelligibility together: the register is wrong for the listener, and a stressed patient cannot follow it first time. This happens even to candidates with strong overall English.

The fix: rehearse plain-language versions of the clinical terms most likely to appear in your profession's role plays before exam day, so you are translating from habit rather than under pressure.

When a patient says they are frightened, confused, or upset, and the candidate continues the planned explanation without responding to it, the recording shows a clinician who did not listen. This is scored specifically under relationship building, separately from whether the clinical content was correct.

The fix: build a short acknowledgement into your habits, a sentence that names the emotion before you return to the task, every time a patient expresses one.

Speaking quickly to fit everything into five minutes, then abandoning sentences partway through, lowers both fluency and intelligibility. Accent is not the issue here; hesitation, self-correction, and speed are what actually make a recording hard to follow.

The fix: slow down deliberately, especially for names, doses, and instructions, and finish each sentence before starting the next one, even if that means covering slightly less ground.

You cannot fix what you cannot hear. Record a practice role play, get it marked against both criteria families, and listen back for the pattern: a consistent gap between your linguistic and clinical communication scores usually points straight at the reason.

Then practise deliberately against your weak family: if clinical communication is behind, drill opening, eliciting, and acknowledging emotion across different cards; if linguistic scores are behind, drill pace and plain-language versions of your own jargon.
