One diagnostic test and three full-length model SAT Subject Tests in Physics reflect the most recent actual tests in length, subject matter, and degree of difficulty. All questions are answered and explained. New self-assessment guides after each test are designed to help test-takers improve their scores. An extensive subject review covers all topics on the SAT Subject Test, including mechanics, thermodynamics, electricity and magnetism, atomic structure, and more. The authors also explain the methodology used in solving physics problems, present a basic math review, provide additional practice questions with answers, and offer test-taking tips.
