Welcome to MOPper World! This website is dedicated to the hard-working math students who participated in the Mathematical Olympiad Summer Program, or MOP (often incorrectly abbreviated MOSP, but that term has other meanings).

MOP is a four-week three-and-a-half week three week camp every year in Lincoln, Nebraska where the 30 winners of the USAMO spend hours every day doing math. At least, that’s what the Zumbot would like you to think. But MOP is about more than just math! This website is a collection of literature, pictures, and other material from the fun side of MOP.
