• Request politeness: てくれない (casual) < てくれませんか (polite) < ていただけませんか (very polite/formal). • Summary: てくれませんか is appropriate for most daily situations with strangers or semi-formal contexts.
The JLPT rarely asks whether you recognise a pattern — it asks which of several similar patterns fits. These are the ones てくれませんか is tested against.
ていただけませんか uses the humble もらう→いただく and is more formal/deferential; てくれませんか is polite but a step less formal.
てくれない is the casual peer-level version; てくれませんか adds ます-politeness for strangers or semi-formal settings.
てもらえませんか frames the favor from the speaker's receiving side and is roughly equally polite; てくれませんか frames it from the doer's side.
