Exam Materials

Course Introduction

Advanced Placement Physics (College Level) is a rigorous course designed to provide students with a deep understanding of core physics concepts equivalent to a first-year college physics sequence. The curriculum covers a broad range of topics, including mechanics, electricity and magnetism, thermodynamics, waves, and modern physics, with an emphasis on conceptual understanding, problem-solving skills, and experimental techniques. Students engage in laboratory work, mathematical modeling, and critical analysis of scientific data to develop their ability to interpret and predict physical phenomena. This course prepares students for success on the AP Physics examination and equips them with a strong foundation for further study in science, engineering, or related disciplines.
