Continuity mistake: When Cassie is in the headmaster's office, her red pencil case keeps changing position from being held up clutched to her chest with her folder, to being in her lap.
Continuity mistake: Cassie is walking at Campus and is run into by 2 boys. She drops her art drawings on the ground. 1 boy attempts to help her pick them up but she says no thanks. After she picks them up and during her talk with her teacher, the order of the drawings changes between shots, from pencil drawings to a color painting of a inverted figure back to the pencil drawings.
