In general, the objective events follow a set organizational outline from year to year. Language and literature focuses on a single novel or a set of plays in addition to multiple short literary selections which tend to be poems or excerpts from short stories. The art and music sections include several selections with which students must familiarize themselves in addition to historical information. Economics remains fairly static; 85% of the material focuses on a standard course of macroeconomics and microeconomics and the remaining 15% focuses on the year's topic. For example, in 2005 the themed material covered the economics of ancient Egypt and Rome. Science and social science reflect the season's theme. Unlike the other events, there is no basic information that carries over. The math curriculum has varied as well, occasionally dropping and adding new subjects or shifting the weight of particular subjects.
