My Little Pony: Equestria Girls - Better Together S01 E09 A Little Birdie Told Me

In Cranky Doodle's class, Mr. Doodle administers a pop quiz to his students. As the students begin, Trixie Lulamoon catches Fluttershy talking math with her bird friends and openly accuses her of cheating on the quiz. Fluttershy explains that she was just settling an argument about nests, but Trixie doesn't believe her. So Fluttershy goes up to the chalkboard and solves a complex math equation without the help of her bird friends, much to Trixie's embarrassment. Later, Trixie approaches the birds and asks one of them to be her tutor.
