Her original last name was "Puckle", but Rowling felt the name "did not suit her at all", and eventually chose the less frivolous "Granger" which made it into the books.

She is disappointed to learn that all end-of-year exams have been cancelled as a special "school treat".

Before the start of term, Professor McGonagall secretly gives her a Time-Turner which allows her to go back in time and attend multiple classes simultaneously.

In the original West End production, Hermione was played by the South African-born actress Noma Dumezweni, also known for her work in Linda, A Raisin in the Sun and A Human Being Died That Night. The choice of a black actress to play the part led to criticism on social media which J.K. Rowling described as being by "a bunch of racists", adding that the books never explicitly mentioned her race or skin colour.

Hermione confunds Cormac McLaggen, causing him to miss his last save attempt during Keeper tryouts and thus ensuring that Ron retains his spot on the Gryffindor Quidditch team.

When they are captured by Snatchers, who are on the hunt for Muggle-borns under the Ministry's orders, Hermione disguises Harry by temporarily disfiguring his face with a Stinging Jinx.
