Continuity: During the lunch scene, when Jake is drinking Gatorade, the amount of liquid continuously changes between shots.

Factual error: Throughout the film several students are seen handling iPhones in ways which iPhones simply do not work. When Tyler walks down the halls of his Orlando high school for the first time, a girl is seen watching a YouTube video of him holding her iPhone in portrait mode (iPhones and iPod touches only view videos in landscape). Later, several students are seen video recording the fighting matches, a feature which iPhone does not have.

Revealing: During the fight scene, when Jake gets out of the car to fight the three guys in the yellow Hummer, Max lifts up his video camera after Jake throws his first punch. But after the fight, when all of the students are watching the fight on the net at school, it shows that Max is recording before the fight even begins.
