The OET Writing sub-test can be challenging as it requires precision and clarity. To help you succeed, we've asked our OET Experts to identify some common mistakes made in the Writing sub-test.  

Misusing ‘rule out’ to mean ‘confirm’

One of the most common mistakes is the incorrect use of the phrase 'rule out.' In medical terminology, 'rule out' means to eliminate or exclude a diagnosis or condition based on evidence. However, many test-takers mistakenly use it to imply confirmation. 

Example 

Case notes: Pneumonia – ruled out (X-ray). 
Incorrect statement: The patient has pneumonia. In this example, the X-ray shows that the patient does not have pneumonia, contrary to what the student wrote. This error can lead to serious miscommunication and demonstrates a fundamental misunderstanding of medical terminology. 

How to avoid this mistake: To avoid this mistake, remember that 'ruled out' means the condition has been excluded based on evidence, not confirmed.  

Correct statement: Pneumonia has been ruled out by an X-ray. 

Confusing ‘complaint’ with ‘compliant’

Another frequent error is the misuse of 'complaint' instead of 'compliant.' This mistake often occurs due to a typo or a lack of understanding of the two terms, which are spelled similarly but have different meanings. 

Example 

Case notes: Medication - taking regularly as per instructions. 
Incorrect statement: The patient is complaint with their medication. In this instance, 'complaint' incorrectly suggests that the patient is unhappy with their medication. The correct term should be 'compliant,' which indicates that the patient is following the medication instructions properly. 

How to avoid this mistake: To prevent this error, carefully proofread your writing and ensure you're using the correct term. If necessary, use spell-check tools but remember they may not catch context-specific errors. Practice differentiating between similar-sounding medical terms to build your confidence. 

Correct statement: The patient is compliant with their medication. 

Misusing ‘advice’ instead of ‘advise’

The third common mistake involves confusing 'advice' (noun) with 'advise' (verb). This error often arises from a typo or a lack of familiarity with the grammatical distinction between the two. 

Example 

Case notes: Smoking - methods to quit discussed. 
Incorrect statement: The patient was adviced to quit smoking. In this example, the correct form should be 'was advised' to maintain grammatical accuracy. 

How to avoid this mistake: A helpful tip is to remember the difference is to picture the 'ice' at the end of the noun, advice, as a physical thing (frozen water). So, 'advice' is a thing that you can give or take. 'Advise' is the action itself. For example: I advise you to stop smoking. 

Additional tips to improve your writing 

Apart from avoiding these common mistakes, here are some additional tips to enhance your writing skills for test day:  

Understand the case notes 

Thoroughly read and comprehend the case notes provided. Highlight key points and ensure you understand the patient's condition, treatment plan, and any instructions given. 

Practise writing letters

Use formal and professional language 

Your writing should reflect a professional tone suitable for a healthcare setting. Avoid colloquial expressions and ensure your language is clear and concise. 

Manage your time 

Time management is crucial during the test. Allocate time for planning, writing, and proofreading your letter. Practising under timed conditions can help you get used to the pace required.
