Emma Watson has been forced to turn down film roles in order to concentrate on her university finals.
According to a source, the 23-year-old actress is in demand with Hollywood directors but she has so much to focus on her studies, that she has had to pass on a few things, the Mirror reported.
The source added that it's tough but the 'Harry Potter' star believes it was the right thing to do, as she simply can't do everything.
