See below for summer information from Northern and Huntingtown High Schools. Each school has specific directions and resources for the summer assignments. I would recommend getting the AMSCO Advanced Placement United States History textbook to prepare for the AP Exam at the end of the year. (See each school's directions for how to do so.) It is not required, but it is recommended, to get this book. Neither NHS nor HHS requires AP students to take the AP Exam at the end of 9th grade, but it is a good experience to do so.
