When Sylvester wants DJ to lead the step at nationals, DJ tells Sylvester that he has waited for four years to beat Gamma Mu. In earlier scenes we can see that DJ has on a pledge jacket that says Spring 06 and Sylvester has one that says Spring 04. If Sylvester waited four years then his pledge jacket should have said Spring 02.
When Mu Gamma Xi first confronts Theta Nu Theta in the yard, a banner declares the Wolves as 2006 champions. Later, when DJ joins the pythons, his pledge jacket says "Spring 06." If the Wolves had already won the 2006 championship, the semester in which the movie takes place could be no earlier than Spring 2007.
When April goes to the frat house to confront DJ she has only her car keys in her hand. However, as she enters the house she is holding a shoulder bag.
In the first scene with DJ in his room, Rich changes shirts and picks up two hats, a green Atlanta Braves hat, and a green beret. Rich leaves the room wearing his green beret; yet later at the barbecue he is seen wearing the green baseball cap.
When DJ nearly runs April over with the lawnmower she removes an ear-bud from her right ear to hear him over her iPod. Depending on the angle she'll either have both, one, or none of the ear-buds in.
Movie connection really - can't get there on the site -
In a rehearsal sequence, a banner for Morris Brown College is seen.

The two sides square off in an official competition, a tie is declared and they face off.
At the nationals, TNT crew come down in a box, from which the assume positions. In the next scene, on the stage there is no track of the boxes pieces that fell apart.
