Emma Watson turning down film roles over exams

'Harry Potter' star Emma Watson is reportedly having to turn down film roles because she's studying for her final exams.

The 23-year-old actress is currently in the middle of swotting for the tests, which start next month, as the culmination of her English degree at the revered Brown University in Rhode Island, US.

A source told the Daily Mirror: “Emma is in demand with Hollywood directors but has so much to focus on with her studies, that she has had to pass on a few things – she simply can’t do everything.

“It’s tough but she believes it was the right thing.”

It would certainly appear that she is deep in the revision zone.

Earlier this month she tweeted a picture of her desk and laptop as she was getting stuck in, lending some encouragement to others in the same boat.

Watson was also a visiting student at Worcester College, Oxford, in 2011 and 2012.

She's the only member of the core Harry Potter threesome, comprising herself, Daniel Radcliffe and Rupert Grint, to take up higher education.
