While she may be best known for her role as Hermione Granger in the Harry Potter films,Emma Watson would rather be known for something else—her mind.

The 18­year­old British actress intends to put her acting career on hold to pursue higher studies at a university after she finished filming the final installment,Harry Potter and the Deathly Hallows.

Watson,whose parents are both Oxford graduates,recently scored straight A's in her A­levels. She is now on a gap year before starting university.

Earlier this month,Watson applied to two of the top universities in the United States—Harvard and Yale. She admitted that Harry Potter series has brought her fame and financial security(经济保障).She has made more than £ 10 million so far,but now she “has a need to study”.

“I think the entertainment business is such a temperamental one. One minute you're up there and the next—nothing,”she said.

Watson is growing up in front of millions of viewers(观众).She was only nine years old when she started playing the role of Hermione. And the way she figured out how to deal with media attention is “try not to read too much of what is said and try to distance myself a bit from it”.

Watson has other interests. These include,interestingly,fishing and she has helped raise money for the Wild Trout(鳟鱼)Trust.
