Aaron Carter isn’t like other 12-year-olds. He doesn’t go to school, and he’s already got a job. He is a big pop star. A few years ago he started his singing with Crazy Little Party Girl, which became a hit at once. Now he goes around the world and his songs are in the tops.

Because he’s traveling around all the time Aaron doesn’t have to go to school, but don’t envy him too much---- he still has to do lessons and homework. And he is good at learning.

“I have to fit my schoolwork around my singing,” he explains. “But I’m lucky because I have a private tutor who travels with me. I sometimes have to have lessons on a plane. That’s really interesting!”

Aaron’s favorite subject is math but he hates history. He knows clearly that having a good singing career doesn’t mean he can go without schoolwork.

“It would be easy to think that I don’t need to do well in exams, but that would be crazy,” he says. “It’s important to get my qualifications（资格）so that I have something to fall back on. Besides, it’s interesting to learn about other people and cultures.”

Aaron’s favorite type of music is rock’n’roll. “The best thing about being a singer” he says, “is that you get to travel all around the world. But the worst thing is that you’re away from home so much that you don’t get to see your friends or family.”
