Frequently asked questions

Will fancier vocabulary boost my band? +

Only when used precisely. Examiners reward fit, not flash. Replacing 'said' with 'reported' fits a clinical context; replacing it with 'verbalised' usually doesn't.

Does this hurt the Conciseness criterion? +

It can if you over-upgrade. The tool also flags wordy alternatives to avoid.

Are the suggestions UK or US English? +

Suggestions default to UK healthcare phrasing (used by the NHS, NMBI, AHPRA in writing). Toggle to US for ECFMG-bound candidates.

Is there a list I can study? +

Yes — see our OET vocabulary list and collocations guides for systematic study.
