CHS offers advanced placement classes that are certified by the College Board. Through college-level AP (Advanced Placement) courses, you enter a universe of knowledge that might otherwise remain unexplored in high school; through AP Exams, you have the opportunity to earn credit or advanced standing at most of the nation’s colleges and universities. The only requirements are a strong curiosity about the subject you plan to study and a willingness to work hard. Just a few reasons to sign up: gain the edge in college preparation, stand out in the college admissions process, and broaden your intellectual horizons. Students are required to sign an AP course contract. Please understand that you will not be allowed to drop an AP course once you have enrolled in it.
