The student-friendly style of the book makes the content accessible without sacrificing either breadth or depth of coverage. The text’s informal writing style, emphasis on problem solving, and state-of-the-art media package make this book an ideal fit at schools with large class sizes and a wide range of student abilities and backgrounds. The authors’ goal was to create a complete package (text + media + supplements) which would challenge the better-prepared students and provide support to the lesser prepared students, giving ALL students a chance to succeed. 4e welcomes a new co-author Fred Senese, Frostburg State University, the creator of the award-winning General Chemistry Online and Ask Antoine (the most hit general chem web resource in the world with over 15 million hits/year). In addition to creating the new Brady/Senese website, he has also worked with Jim Brady to do significant revisions in the text.
