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.
Why Most Candidates Fail OET Writing
These are the patterns we see in submitted letters every day. Each one silently costs marks across the six OET writing criteria.
Weak or missing purpose
The letter starts without clearly stating why it is being written. A letter with a late or unclear purpose loses marks under Purpose.
Information overload
Too many case notes are included without prioritisation. Key clinical details get buried under irrelevant information.
Wrong tone for the reader
The letter sounds either too casual or too rigid. Genre & Style rewards a tone that matches the professional context.
Poor paragraph structure
Information is scattered across paragraphs with no logical flow. The reader cannot follow the clinical reasoning.

Frequently asked questions
Price, turnaround, who marks your letter, and what a correction can and cannot do.
What is OET writing correction, and who is it for?
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.
How much does OET writing correction cost?
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.
How fast will I get my letter back?
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.
Who corrects my letter, and what are their qualifications?
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.
Is my letter corrected by a person or by AI?
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.
Can I have one letter corrected without buying a course?
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.
Does a correction guarantee that I will pass?
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.
What if I do not understand the feedback?
Contact us and we will explain any part of your correction at no extra charge. The refund page sets out the full refund terms.
Do you accept handwritten letters?
Yes. Photograph or scan the letter clearly. As long as the handwriting is legible, handwritten and typed letters are corrected to the same standard.
