From article: > The marker's notes - seen by the BBC - raise concerns about the "polished/uniform tone" of the work, noting the "consistent flawless grammar and similar sentence structure with no variation in style". The notes also mention a "formulaic paragraph structure that follows a typical AI pattern of 'general claim, the example/result, and conclusion'." Other observations point to repetitive phrasing and a lack of "nuanced critique" as well as a high usage of "em" dashes, a type of punctuation thought to be favoured by AI models.

Judging by the given remarks I see nothing here which proves AI use.
