The requirement for high school graduation in Arizona will be three (3) science credits. These credits may be earned by taking any combination of our course offerings. Entrance to all three Arizona Universities encourages students to be exposed to at least three lab sciences which are to be completed in three of the four disciplines offered. The four disciplines offered are Life Science (L), Earth Science (E), Physical Science (P), and Chemical Science (C). Students bound for a 4-year university must take at least 1 from each of 3 different disciplines. Pre and AP courses count as any discipline.
