In summary, the AP Physics 1983 Exam is a 3-hour exam that consists of two sections: a multiple-choice section and a free-response section. The multiple-choice section has 40 questions and is worth 50% of the total exam score, while the free-response section has 3 questions and is also worth 50% of the score. The exam covers topics in mechanics, electricity, and magnetism, and a scientific calculator is allowed, but cannot have any built-in or downloaded programs. The exam is scored based on the number of correct answers for the multiple-choice section and a rubric for the free-response section. A passing score is 3 or higher, which may earn college credit.
