Children's/ YA Fantasy book about a boy who discovers he has a unique magic ability and ends up in a world/school(?) where everyone has their own unique ability

[Jacob]

I read this book in the mid-2000s and I think it was newish. All the characters have unique magical abilities and are competing in some kind of tournament or something (?) against other teams. I vaguely remember a competition where they are traversing a maze trying to compete with other characters. I also remember there being a character that plays some magical ball sport and his ability allows him to visualize the exact trajectory he needs to score or something like that. I do believe that it turns into a series so some of the details may be mixed up.

Thank you for your help!
