Why this happens to PhD applicants

Without a topic sentence, the examiner reaches the middle of the paragraph before knowing its point. The logic may exist, but it is not visible, and organisation is harder to credit.

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

Long, complex paragraphs lose the single central idea.

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

Fix it in four steps
