<p>Would you say that the only difference is that you have to come 1 hour more for the 4 credit one, which may not even matter that much if the attendance checking is poor?</p>
<p>Usually, 4 credit hour classes tend to meet longer and cover more material. And very few courses at Michigan have poor attendance checking. A professor teaching a class with fewer than 100 students will usually know who misses class on a frequent basis.</p>
<p>one wastes 3 credits worth of ur time and the other wastes 4, lol</p>
