What to check first
Check Task Response and Coherence against criteria before deciding to polish.
Judge whether correction, revision, polishing, score tools, teacher feedback, courses, or score-gap repair plans can produce verifiable diagnosis, evidence, and rewrite steps.
Any writing service should help you repair your own essay, not replace your answer.
When an essay is off-task or underdeveloped, polishing makes the problem smoother but may not raise the score.
If feedback only swaps words without discussing prompt and paragraphs, it is polishing, not writing diagnosis.
Check Task Response and Coherence against criteria before deciding to polish.
Rewrite claim and development sentences first, then adjust collocation and sentence patterns last.
These pages explain the Banfen Writing diagnostic and blocker-repair method, Task 1 overview, Task 2 development, and common score blockers.
Submit the prompt and essay, confirm the main blocker, scoring criterion, and essay evidence first, then decide whether you need correction, a course, a tool, or a longer repair plan.
