Last year, double the number of Ohio juniors took Advanced Placement courses than a decade ago and college-exam prep courses are becoming more popular, facts that have many students saying their third year of high school is their hardest yet and education experts agree. "If you look across the board, but particularly in Ohio, this is not going to be your parents' or grandparents' junior year," says David Griffith, ASCD's public policy director. "They're taking more math, more science, more social studies. They're taking more college-prep courses across the board. Junior year is when they're dotting their i's and crossing their t's and getting their fundamental academic foundation down."
