Want to be a hero and postpone your exam?  Easy.  Just start a flash mob.

During an exam at the University of Toronto, a bunch of first year engineering students decided to entertain the class with an impromptu performance.

This is what I call winning first year university.  But then again, if you actually studied for the exam, this would have been kind of inconsiderate.

Louis Tomlinson proved yet again why he’s so crushable when he surprised his girlfriend Eleanor Calder just before her exam. I mean, the guy is busy enough jet-setting around the world and performing to screaming fans, but he still fit in time to wish his girlfriend good luck on her exam… in person.

It appears his presence served more than one purpose. Naturally, he was a good luck charm but Calder joked on Twitter that he helped wake her up. Calder goes to Manchester University and has been dating Tomlinson for seven months.
