McGraw-Hill’s Homework Manager is a Web-based supplement that duplicates problem structures directly from the end-of-chapter material in the book using algorithms to provide a limitless supply of online self-graded practice for students, or assignments and tests with unique versions of every problem. McGraw-Hill’s Homework Manager is also a useful grading tool. All assignments can be delivered over the Web and are graded automatically, with the results stored in your private gradebook. Detailed results let you see at a glance how each student does on an assignment or an individual problem—you can even see how many tries it took to solve the application.
