Why human feedback matters
AI tools are useful for grammar, but they cannot assess clinical appropriateness or professional tone accurately. Our teachers read every word to ensure you meet the official OET marking criteria across all six assessment areas.
OET writing is assessed by trained examiners using criteria developed in partnership with Cambridge Boxhill Language Assessment Trust. Since 2014, we have corrected over 11,000 OET and IELTS letters, and 97% of students who complete 3 or more corrections show measurable score improvement.

Flexible turnaround
24h, 48h, and 72h correction speeds available.
Clinical logic review
We check if you have selected the relevant case notes for the specific reader.
No AI bots
Your letter is reviewed by a qualified teacher, not software.
Corrections identify logic gaps that automated tools miss.
"The most common pattern we see is candidates with strong grammar who still score below Grade B. They include too much information, miss the purpose, or misjudge the tone. These are the areas where human feedback makes the real difference — no AI tool can reliably assess clinical appropriateness."
