A doctor's referral letter, corrected the way we correct every letter: a score out of 500, your six OET marks, each mistake fixed and explained, and a PDF report to keep.
You wrote
I am writing to refer Mr Hughes, 58-year-old accountant, who is complaining from chest pain since three weeks.
Better
I am writing to refer Mr Hughes, a 58-year-old accountant, for urgent assessment of suspected stable angina.
Why: The opening must give the reason for the referral and its urgency, not only the symptom. Dr Lee should know what you want from her in the first sentence.
Left out of your letter
Better
His total cholesterol was raised at 6.8 mmol/L.
Why: The case notes give a raised cholesterol. It is a cardiac risk factor, so the cardiologist needs it. Leaving it out costs you on Content.
You wrote

Better
a 58-year-old accountant
Why: A singular countable noun needs an article. Rule: a/an before a singular job or description the first time you mention it.

Good English is not enough. Most candidates who fail OET Writing have acceptable grammar — they lose marks on structure and relevance. According to the official OET assessment criteria developed by CBLA (Cambridge Boxhill Language Assessment, which owns the OET), writing is scored across six criteria — and only one of them, Language, relates to grammar and vocabulary.
These are the patterns we see in submitted letters every day. Each one silently costs marks across the six OET writing criteria.
The letter starts without clearly stating why it is being written. A letter with a late or unclear purpose loses marks under Purpose.
Too many case notes are included without prioritisation. Key clinical details get buried under irrelevant information.
The letter sounds either too casual or too rigid. Genre & Style rewards a tone that matches the professional context.
Information is scattered across paragraphs with no logical flow. The reader cannot follow the clinical reasoning.

Each profession writes different letter types with different conventions. Our correctors grade to the profession you're registering in.
Price, turnaround, who marks your letter, and what a correction can and cannot do.
OET writing correction is feedback on a practice letter you have written for the OET Writing sub-test. You send your letter with its case notes; a person marks it against the six OET writing criteria and returns corrections and a score estimate. It is for doctors, nurses and other healthcare professionals preparing for OET.
A single letter costs $15 with 72-hour return, $18 with 48 hours or $22 with 24 hours, in US dollars. Packs of 3, 5, 8 or 10 letters cost less per letter: a 10-letter pack starts at $65. The pricing page lists every pack and speed.
You choose the turnaround when you order: 24 hours, 48 hours or 72 hours. A single letter costs $22, $18 or $15 at those three speeds. If your exam is close, choose 24 hours and send the letter today, so you can use the feedback on your next practice letter.
Letters are corrected by Dr Mariam, who holds a PhD in English and has taught exam writing for more than 20 years, together with her trained team. Dr Mariam is not an OET examiner, and this service is not affiliated with OET or CBLA. Feedback follows the six published OET writing criteria.
Every paid correction is done by a person, not by AI or an automated grammar checker. Dr Mariam's team marks your letter against the six OET writing criteria and writes sentence-level corrections. The free tools on this site do use AI; they are for practice and are separate from a paid correction.
Yes. You can buy a single letter correction for $15 to $22, depending on turnaround, with no course and no pack. Packs of 3 to 10 letters and the OET Writing Pass Course are separate products, and neither is needed to have one letter corrected.
No. No service can guarantee an exam result, and you should be careful with anyone who promises one. A correction shows where your letter loses marks under each criterion and how to fix it. Most students send three to five letters, so they can apply the feedback before the exam.
Contact us and we will explain any part of your correction at no extra charge. The refund page sets out the full refund terms.
Yes. Photograph or scan the letter clearly. As long as the handwriting is legible, handwritten and typed letters are corrected to the same standard.
