Today I ran across a humorous look at final exams from a law professor. It’s a bit dated–1971–but most of the rules (or anti-rules) still hold true (except the rule about writing illegibly–although I guess you could opt to hand write your exam).
Thirteen Rules for Taking Law Exams, 24 J. Legal Educ. 76 (1971) (this link works for the BYU law community, but you can find the article on HeinOnline if your school has access).
