The percentage of high school graduates who have taken Algebra II has more than doubled in the last two decades. Algebra II is a prerequisite to trigonometry and calculus–both required for careers in science, math, and business. There is also an increased emphasis on algebra and advanced algebra in standardized tests such as the all-important ACT and SAT.
