We hope that you enjoy the 25th BAMO. If you have never participated in an exam like BAMO, it can take some adjustment. Remember, there are only five questions, and you have a four-hour time limit! You are encouraged to think deeply, and then to carefully write up your solution.

Take a look at this nice essay, written by Richard Rusczyk and Matthew Crawford of the Art of Problem Solving, to get some advice about how to write a solution that is readable, clear, and—hopefully—correct!
