In a test, there's no one telling you that you can't look at the book, says Ariel Hatten, 20, a junior and nursing major who considers her online class an easy A.
"No one enforces you to do the right thing" in an online course, Ms. Hatten says. "It's at your discretion. I care about my grade, so if I don't know the answer, I'm not gonna let myself fail when I have an opportunity to look in the book."
