<p>A college credit is defined as three hours’ work per week; one in class and two outside. That’s why adding a three-hour lab to a class only results in one additional credit.</p>
<p>This means that 12 credits translates to an average of 36 hours’ work a week. That’s why 12 credits is considered full time; it’s the equivalent of a full-time job.</p>
<p>If you have a course that meets three hours a week for 3 credits but doesn’t require six hours of outside work a week to keep up, consider yourself lucky. Other courses may require more time. Also, individual students require different amounts of study time. It does no good to complain that three hours a week per credit is excessive, any more than it does to complain that 26 miles is too long for a marathon. They are what they are.</p>
<p>The one thing you can count on is that a few hours of cramming before the final will not give good results.</p>
