<p>As everyone else has pointed out it depends on the class and your efficiency in work. I had one 3 credit class in the fall semester whose hws would literally take me 10-12 hours a week to complete and midterm & final projects would take up to 27 hours over the course of 2 weeks and another that would suffice with 0 hrs of hw and 1-2 day cramming before a test. Mind you, I got a lower grade in the former class.</p>
