Common Mistakes OET Candidates Make and How to Avoid Them

In healthcare communication, even small language errors can lead to serious misunderstandings. A poorly written referral or unclear instruction in a discharge letter may affect patient safety, delay treatment, or result in incorrect care decisions. That is why the OET Writing sub-test is not just about English accuracy—it is about clear, professional, and clinically safe communication. 🏥

Below are the most common mistakes OET candidates make and how to avoid them.

1. Using informal language in medical letters ⚠️

Many candidates use casual expressions because they translate directly from everyday English.

Incorrect:
“The patient is feeling really bad and needs help ASAP.”

Correct:
“The patient is in significant discomfort and requires urgent medical attention.”

📋 Why it happens: Candidates confuse conversational English with professional clinical tone.

2. Incorrect medical terminology ⚠️

Using the wrong term can completely change clinical meaning.

Incorrect:
“High sugar pressure”

Correct:
“Elevated blood glucose levels”

📋 Why it happens: Direct translation from native language or lack of medical vocabulary.

3. Poor structure in referral/discharge letters 📋

Some candidates write information in random order instead of following a logical format.

Incorrect:
Mixing symptoms, history, and request without clear paragraphing.

Correct:

• Introduction (patient details & purpose)
• Medical history
• Current condition
• Action required

📋 Why it happens: Lack of familiarity with OET letter conventions.

4. Misunderstanding case notes ⚠️

Candidates sometimes misinterpret abbreviations or key clinical information.

Incorrect:
Interpreting “SOB” as emotional distress instead of “shortness of breath.”

Correct:
Accurately using: “The patient reports shortness of breath (SOB).”

📋 Why it happens: Limited exposure to clinical abbreviations and case formats.

5. Grammar errors affecting clarity ✍️

Small grammar mistakes can make instructions unclear.

Incorrect:
“She have pain in chest and need scan.”

Correct:
“She has chest pain and requires a scan.”

📋 Why it happens: Interference from native language grammar structures.

6. Overcomplicating sentences 🎯

Some candidates try to sound “advanced” by writing overly long sentences.

Incorrect:
“The patient, who was admitted yesterday because of severe symptoms that started suddenly, is currently being observed in the ward and may require further treatment depending on his condition which is unstable.”

Correct:
“The patient was admitted yesterday due to sudden severe symptoms. He is currently under observation and may require further treatment.”

📋 Why it happens: Belief that longer sentences show higher English level.

How to Improve Your OET Writing Skills ✍️

• Practice writing with a strict clinical structure.
• Build a personal glossary of medical terminology.
• Learn common abbreviations used in case notes.
• Focus on clarity, not complexity.
• Review model answers regularly.
• Time yourself to simulate exam conditions.

In the OET exam—and in real healthcare settings—clarity saves lives. Avoiding these common mistakes will not only improve your score but also ensure your communication is safe, professional, and effective. Remember: in medical English, accuracy is more important than complexity.
