Fark spotted this story in the UK's Sun about an error discovered in the Harry Potter series:
JK ROWLING has been forced to correct a plot blunder in a Harry Potter book — after fans spotted it.
The author credits Hermione Granger with 11 top exam results in the first hardback edition of book six, Harry Potter And The Half-Blood Prince.
But in book five — Harry Potter And The Order Of The Phoenix — we are told she takes TEN examinations.
Publishers Bloomsbury have corrected the paperback edition to give Hermione nine “outstanding” and one “exceeds expectations” in her Ordinary Wizarding Levels.
In the uncorrected version, Harry gets seven OWLs with honours, Ron also achieves seven, while Hermione gets ten “outstandings” and one “exceeds expectations”.
One of the first fan websites to spot the error was www.mugglenet.com. It is believed to be the first blunder in the Potter series, which has earned JK, 41, more than £500million...
Bloomsbury admitted last night: “We can confirm there was an error.” A publishing source said: “With a series like this it is inevitable a blunder like this would occur. It is just remarkable it didn’t happen earlier. It was only a small error and easily reversible.”
Hermione actress Emma Watson, 17, is a real-life brainbox. She got eight A*s grades and two As in her GCSEs.
