According to the annual National Survey of Student Engagement, the average college senior hits the books for about 15 hours a week. But the amount they devote to reading, reviewing notes, or participating in study groups varies significantly depending on their major. Engineering students rack up the most time—19 hours per week—while their business and social science major peers study a relatively paltry 14 hours per week.

The report also reveals that students aren’t meeting faculty expectations for how much time they should spend studying. Social science professors expect students to put in a minimum of 18 hours per week, but they're only studying 14 hours. And they work outside jobs almost as much as they study—an average 13 hours a week. Business professors expect students to study 15 hours a week, but instead of hitting the books for an additional hour, they're working a whopping 19 hours a week.
