LONDON — Taliban attack survivor Malala Yousafzai says she is thrilled to have the chance to speak out for girls' rights as she travels to Norway to pick up her share of the Nobel Peace Prize.

The youngest Nobel Prize winner ever attended classes Monday before leaving her home in central England for the Oslo ceremony. She told the Associated Press she will use her acceptance speech Wednesday to say that no child should be denied an education.

"It's really a moment of happiness," she said. "This is such a big opportunity for me to speak up. I want to tell the world leaders: Why don't you do something? These children, my sisters, they are out of school. They cannot get an education."

The 17-year-old said she had been concentrating on her difficult school exams in recent weeks — she is pleased to have gotten As and Bs —and has only focused on writing her Nobel speech in the last week.

She was shot in the head by a Taliban gunman over two years ago for insisting that girls as well as boys have the right to an education. She had been attending the Khushal Public School, owned by her father, even after the Taliban overran her town in the volatile Swat Valley in Pakistan.

She survived several complex operations and benefited from expert British medical care, choosing to stay in England for schooling after her recovery.

To spotlight her crusade, Malala has invited four girls and a young woman who have fought for education rights in Syria, Nigeria and Pakistan to join her delegation.

"I'm really happy my friends are coming," she said. "I feel I am speaking on their behalf. It is important they are able to join me. This is a very big platform."

She will share the $1.1 million Nobel Peace Prize with Indian children's rights activist Kailash Satyarthi.

The teen's only complaint? She has to bring her two younger brothers to Oslo.

"I wanted not to bring them, but they are my brothers, I had to," Malala joked.
