You may use your class notes and Feynman

This is the sort of hack that Feynman himself would have pulled, back when he was an undergraduate.

Funny but sound like a urban legend.

bloody briliant, a much better exam hack than pointless puns.

He can't have been the only person in the class who had the thought. I would have; I just wouldn't have dared.<p>True or not, funny story.

Even if they had explicitly written <i>Feynman's Lectures on Physics</i> on the exam, the students could have asked Feynman to give a special lecture which happens to cover all of the exam material.

Half an hour, why it took him so long?
