Ungifted by Gordon Korman

Donovan is kind of a troublemaker at his middle school. He's definitely not a kid that would get recommended to attend a special academy for gifted students. But after causing a major statue malfunction that destroys his school gymnasium, the superintendent has Donovan's name on a piece of paper on his desk. When that paper accidentally gets submitted to the academy for gifted students, Donovan realizes that it's a great place to hide from the punishment he faces for the statue incident. Donovan definitely doesn't rise to the occasion and become gifted in math and science, but he does make some friends and the gifted kids come to appreciate his laid back style and sense of humor. There's a robot and a pregnant sister that factor into the story to keep things interesting. While I don't think this is quite at the level of Schooled or No More Dead Dogs, this is another fun book about middle school life from Gordon Korman.
