A movie about a girl who changes her friend's name to hers on a test

I only remember a scene from that movie, there are several people taking a test and when the test is over, the people in the back pass the tests forward, until the girl in the front takes the test from the girl who was behind her, and changes a letter of the name, then it passes.

Maybe it was an A in the name, so it only circles to become an O. That’s about it.
It must be around 2000.
