This updated manual presents a diagnostic test and four full-length practice tests that reflect the actual "SAT Subject Test in Chemistry" in length, question types, content areas covered, and degree of difficulty. All practice tests are presented with answers and explanations, as are the 250 test-like questions at the end of each chapter. New with the 9th edition is a CD-ROM that presents computerised versions of two additional practice tests with automatic scoring, answer explanations, and a diagnosis of strengths and weaknesses by subject area. The manual's subject review covers all test topics, including structure of matter, states of matter, reaction types, stoichoimetry, equilibrium and reaction rates, thermochemistry, descriptive chemistry, and laboratory skills. Marginal notations of helpful hints direct student attention to important items.
