Why this happens to PhD applicants

Candidates memorise impressive words and idioms and place them where they do not fit. The examiner notices the mismatch, and errors in less common words are counted against the response.

Why this affects PhD applicants: research writing is cautious and hedged, which can make a Task 2 position look uncommitted.

Discipline vocabulary can crowd out simple natural language in general topics.

A strength to build on: Practice with structured argument and evidence is already strong.

Fix it in four steps

Replace any word you cannot define and use in two sentences with a simpler accurate one.
