Goofs

In the scene where Mel is taking Tracey and Evie to Brooke's, it's clear that both girls are in the backseat. But when they get to Brooke's house, Tracey gets out of the front.

When Evie and Tracy are getting out of the car at Melrose, the same girl in a yellow tank top walks by in each shot. Once when they are still in the car, and once when they are walking away from the car.

At Melrose, when Tracey's mom drops them off and the girls get out of the car, you can see them through the window. But when a car drives by the girls have disappeared.

After Evie and Tracy get back from the park and go in to Tracy's bedroom, through the window you can see Mel get up to go talk to Tracy. It then cuts from the bedroom back to Mel still sat on the couch.

During the intervention scene at the end of the film Tracy runs into the kitchen, and a calendar is visible, showing the date as October 2003. The scene where Tracy and Evie hit each other was said to be four months after the first day of school, which means it happened in late December or early January, and their injuries aren't healed when the intervention takes place, so the two events must have occurred close together. That's also far too early for a student to be told she will fail a grade no matter what she does, which happens immediately before the intervention scene.
