A proven learn-by-doing approach to chemistry essentials Some 50 percent of America's 15 million high school students take chemistry before graduating, and chemistry courses are staples at community and four-year colleges as well. Targeted at students enrolled in general chemistry courses in high school and college, this book applies a highly effective problem-solving approach to basic chemistry, including a pretest to help pinpoint weak spots, chapters that review key chemistry topics, extensive problem sets with solutions, and a customized full-length exam at the end.
