OET Score: Tips to Reach Grade B in Every Sub-Test

The OET score report arrives as a number between 0 and 500 for each sub-test, with a corresponding letter grade from A (highest) to E (lowest). Grade B — which maps to a score of 350 or above — is the threshold required by most healthcare regulators in Australia, the UK, New Zealand, and Ireland.

Some boards, and some visa pathways, require Grade B overall with no single sub-test falling below Grade C. Checking the exact requirements of your specific registration pathway before you sit the exam saves you from the unpleasant surprise of passing three sub-tests and failing on your weakest.

The four OET sub-tests are not equal in difficulty for most candidates. Listening and reading follow a standardized format where answers are marked right or wrong. Writing and speaking are assessed by trained human examiners working from detailed marking criteria. That distinction matters enormously for preparation strategy: improving at listening and reading is a question of skill development and exam technique; improving at writing and speaking requires understanding what examiners reward and learning to produce it consistently under time pressure.

Most healthcare professionals who take OET have a reasonable level of general English competence — the challenge isn't the language itself but the specific academic and professional register the exam demands. Listening to a consultation and identifying discrete information points while managing competing cognitive tasks. Reading a complex healthcare text under time pressure and synthesizing across two or three sources. Writing a referral letter that satisfies both clinical and language criteria simultaneously. Speaking in a clinical role-play with a trained interlocutor who creates realistic patient scenarios. Each requires targeted preparation that general English practice alone won't provide.

This guide covers the in detail, explains what examiners look for in writing and speaking, and provides practical preparation tips for every sub-test. Whether you've already sat the OET and want to understand your results, or you're preparing for your first attempt, the approach you take in the final weeks before has a significant impact on your outcome.

One thing candidates consistently underestimate is how much the professional register of OET differs from everyday English. The exam isn't testing whether you can communicate in English generally — it's testing whether you can communicate in clinical English professionally. The vocabulary you use in a referral letter, the way you explain a diagnosis to a patient, the way you manage a difficult consultation — all of these have conventions that are specific to healthcare professional practice, and OET assesses adherence to those conventions. General English proficiency gets you through; clinical professional language is what earns Grade B consistently.

The scoring gap between Grade C+ (300–340) and Grade B (350+) often comes down to consistency rather than ability. Many candidates can produce Grade B-level work in their best moments but drop below that threshold under exam pressure or fatigue. Building exam endurance — by consistently practicing under timed, realistic conditions — is what converts occasional Grade B performance into reliable Grade B scores. Your preparation strategy should prioritize consistent quality over peak performance.

Track your sub-test scores across practice attempts to identify your trajectory. Improving from 290 to 320 to 340 across three attempts shows a clear upward trend that predicts eventual Grade B achievement. Stagnating at the same score across multiple attempts signals that your preparation approach needs to change, not just that you need more of the same practice.

The OET listening sub-test runs approximately 40–45 minutes and contains three parts. Part A consists of two consultations between a healthcare professional and a patient; you complete notes while listening. Part B is a series of six short workplace extracts (ward rounds, handovers, patient interviews) where you answer a single question per extract. Part C presents two long healthcare monologues — talks, lectures, or presentations — with six questions each. Each part tests different listening skills: note-taking, detail extraction, and extended listening for gist and specific information.

The most common reason candidates underperform at listening is spending too long on a missed answer. If you don't catch the information for a note in Part A, write a placeholder and keep moving. The audio doesn't pause for you, and falling behind is far more costly than leaving a blank. In Part C, predict the answer type before the audio plays: is the answer likely to be a number, a profession, a clinical condition, a timeframe?

Predicting forces you to listen with purpose rather than scanning broadly for anything relevant, which reduces cognitive load considerably. Most include authentic listening practice audio — use them to build stamina for the full sub-test length, not just individual questions.

The OET reading sub-test runs 60 minutes and contains three parts. Part A is a speed-reading task: four short texts (270–380 words each) on a single healthcare topic, with 20 fill-in-the-blank questions drawn across all four. You have 15 minutes. It's the most time-pressured component in the entire exam. Part B presents six short workplace texts with a single question each. Part C presents two extended healthcare texts (800–900 words each) with eight questions apiece, focusing on comprehension, text structure, and inference.

For Part A, you don't need to read every text from start to finish. Skim the headings and first sentences of each text first to build a mental map of where different information is located. Then work through the questions systematically, using the text map to navigate quickly to the relevant section. Candidates who read each text in full before attempting questions typically run out of time before completing all 20 items.

In Part C, the extended questions reward careful reading over speed — don't rush these. The answer to each question is usually traceable to a specific paragraph; developing the habit of underlining or annotating as you read significantly improves accuracy under time pressure. Completing authentic under timed conditions is the only reliable way to build the reading speed and stamina Part A demands.

One preparation approach that consistently improves listening scores is active listening practice with healthcare audio away from exam conditions. Listening to medical podcasts, patient consultation recordings, or clinical case discussions while commuting builds the cognitive foundation that exam performance draws on. The ear needs to become accustomed to the pace, register, and clinical content of healthcare English before you can reliably extract specific information under time pressure. Passive exposure doesn't replace structured exam practice, but it dramatically reduces the adjustment period when you encounter authentic OET audio for the first time.

The OET writing sub-test is 45 minutes long. You receive case notes — typically 20–30 lines covering a patient's clinical history, medications, investigations, and treatment — and a task card specifying who the letter is addressed to (a GP, a specialist, a pharmacist, a community nurse) and the purpose of the referral or discharge. You write one letter of approximately 180–200 words. The most important skill isn't grammar or vocabulary — it's content selection. Many candidates include far too much from the case notes, producing long, dense letters that lose marks for conciseness and bury the most clinically important information.

The letter should open with the referral purpose and the patient's key details, then present the most clinically relevant history in a sequence the recipient can act on. Investigations and their results belong in the letter only if they're directly relevant to the referral purpose. Medications belong if they affect the recipient's management decisions.

Routine biographical details, historical conditions unrelated to the current presentation, and procedural descriptions of investigations already completed are often irrelevant and should be omitted. Developing the habit of reading the task card carefully and filtering case notes against that specific clinical purpose is the single most effective writing tip available. After writing your letter, read the task card again — not the case notes — and ask whether every sentence you've written serves the stated purpose of the referral.

Grammar errors in OET writing are assessed for their impact on clinical communication. A minor spelling error in a non-clinical word rarely affects your score significantly. A grammar error that changes the clinical meaning of a sentence — a medication dose, a timeframe, a negation — is heavily penalized because it represents a genuine patient safety risk in clinical communication. Examiners are explicitly trained to focus on errors that impede clinical clarity.

This means your preparation priority should be eliminating errors that create ambiguity, not achieving perfect formal grammar. Candidates who write clearly and clinically, even with occasional minor errors, consistently outscore those who write grammatically perfect letters that aren't clinically relevant. The from specialist preparation providers typically include marked sample letters with examiner-level feedback — using these accelerates writing improvement faster than self-study alone.

The OET speaking sub-test consists of two role-play cards, each lasting approximately five minutes. You receive the role-play card two to three minutes before the speaking sub-test begins, giving you time to read it and plan your approach. The interlocutor plays the patient and follows a script designed to introduce realistic challenges: a patient who is worried, resistant to advice, asking difficult questions, or giving a complex social history. Your job is to manage the consultation professionally, gather relevant information, respond to the patient's concerns, and communicate clinical information clearly.

One underappreciated aspect of OET writing is sentence structure. Examiners reward varied sentence construction — a mix of simple, compound, and complex sentences that flows naturally and avoids repetition. Letters written entirely in short, choppy sentences lose marks for register and sophistication even if the content is accurate. Letters written entirely in long, complex sentences with multiple embedded clauses are hard to read and lose marks for clarity.

The effective OET letter moves fluidly between sentence types: a direct opening statement, a complex sentence presenting the clinical history, a simple statement for the most critical clinical fact, and a closing sentence that communicates the next step clearly. Developing sentence variety through deliberate practice is faster than most candidates expect.

OET speaking scores are heavily influenced by what happens when the interaction becomes difficult. The role-play cards are deliberately designed to introduce friction: a patient who doesn't want to follow advice, a family member who's upset, someone who doesn't understand their diagnosis. How you handle these moments determines a significant portion of your interaction score. The worst response is to ignore the difficulty and continue your clinical agenda. The best response is to acknowledge it, show empathy, and then redirect — exactly what a competent healthcare professional would do in a real consultation.

Interlocutors are trained to follow the script even if the candidate is managing the consultation well. The script includes specific patient behaviors (becoming upset at item three, asking a resistant question at item five) regardless of what the candidate says or does. This can feel unpredictable when you first encounter it in practice, which is why working with a trained OET interlocutor before is particularly valuable.

Recordings of your practice role-plays reveal habits you might not notice during the interaction itself — dominance of the conversation, rushed explanations, missed patient cues — that experienced preparation providers can identify quickly and help you correct. Your strategy should include at least several full speaking role-play sessions with feedback before you sit the actual exam.

Understanding your OET results report is straightforward once you know how it's structured. You receive a score (0–500) and a letter grade (A–E) for each sub-test separately. There's no composite OET score — each sub-test stands alone. Some registration bodies ask for sub-test scores as well as grades; save your full score report for your records. Results are released online approximately 16 days after your test date. If you're waiting for results to complete a registration application, factor this timeline into your planning — don't sit an exam the week before your application deadline.

If you fail one or more sub-tests, the report doesn't provide detailed feedback on which specific questions you missed or which examiner comments affected your writing score. What you do receive is the score, which tells you how far below Grade B you were. A score of 330 (Grade C+) suggests you're close and targeted preparation will likely push you over. A score of 270 (Grade C) suggests more fundamental gaps that require extended work.

In either case, reviewing which part of which sub-test is weakest — through diagnostic — is more useful than simply re-attempting the exam with the same preparation approach. Using quality that include authentic exam-format practice across all four sub-tests gives you the diagnostic data you need to target your preparation effectively.

Candidates who have previously sat IELTS sometimes find the OET speaking sub-test unexpectedly challenging. IELTS speaking rewards fluency, coherence, and range of language across general topics. OET speaking specifically rewards professional consultation management skills — and those aren't the same thing.

A candidate with excellent IELTS speaking scores can fail OET speaking by delivering technically accurate English in a way that doesn't respond to the patient's emotional state, dominate the consultation agenda without checking patient priorities, or fail to close the consultation with a clear plan. Conversely, candidates who work in direct patient care every day often find OET speaking more natural than IELTS speaking because it tests what they actually do at work.
