In general the best way to prepare for a jurisprudence exam is to wake up early the day before, beat your head against a hard surface for a few hours, print out the state law, physically run around it 8 times while banging a pot and Pan while yelling "Oklahoma", watch Paul Blart mall cop 8 times, and then engage in whatever amount of heavy drinking that will produce an incredible hangover but not so much that you're still drunk. Not looking up the testing location until 30 minutes before the exam might also increase your test score.
