me look through the book to find answers so I did more reading.” —student, Northern Illinois University “It was very helpful to get instant feedback Sometimes I would get lost reading the book, and these individual problems would help me focus and see if I understood the concepts.” —student, Temple University “I really like the way MyEconLab took me through the graphs step-by-step The Fast Track tutorials were the most helpful for the graph questions I used the 1-2-3 buttons all the time.” —student, Stephen F Austin State University “I would recommend MyEconLab to a friend It was really easy
