You may take just Mechanics or just Electricity and Magnetism, or both. If you take both, you will receive a separate grade for
each. Each section of each examination is 50 percent of the total grade; each question in a section has equal weight. Calculators are
permitted on both sections of the exam. However, calculators cannot be shared with other students and calculators with typewriter-
style (QWERTY) keyboards will not be permitted. On the following pages you will find the Table of Information that is provided to
you during the exam.
If you are taking
— Mechanics only, please be careful to answer numbers 1–35;
— Electricity and Magnetism only, please be careful to answer numbers 36–70;
— the entire examination (Mechanics and Electricity and Magnetism), answer numbers 1 –70 on your answer sheet.
