‘Hermione, the exams are ages away.’
‘Ten weeks,’ Hermione snapped. ‘That’s not ages, that’s like a second to Nicolas Flamel.’
‘But we’re not six hundred years old,’ Ron reminded her. ‘Anyway, what are you revising for, you already know it all.’
‘What am I revising for? Are you mad? You realise we need to pass these exams to get into the second year? They’re very important, I should have started studying a month ago, I don’t know what’s got into me …’
I know, some people don't like Hermione's uptight infatuation with studying, but I love her. And she does relax more in the later books.
