Studying for an engineering dynamics final, the old "when in doubt, pick C" saying popped into my head, so I decided make a frequency plot of answers for the 4 quizzes we had that term. The prof had B as the correct answer ~50% of the time. At the end of the 2 hour final I had only finished 13 of the 20 problems, so I quickly marked B for the 7 remaining. I got the 2nd highest grade in the class, bumping my grade from a B to an A.

My last year of college I was low on funds, so at the beginning of each term I would go to the school library and see if they stocked any of the textbooks. I could usually find 1 or 2. I'd check them out and keep them the whole term, paying only a $5 late fee - vs. the $100 textbook cost. (In case you think this is inethical, based on the past checkout records, nobody ever checked these books out)

Hack I wish I'd thought of: A college buddy spent the first day of summer vacation going into all the bars in downtown Portland and getting info about their happy hours. He had every day of the week mapped out and got dinner and a beer for $1/night.
