<p>How difficult are Columbia courses. How hard is it to get an A? How many hours of work are there to do a week? Any comments about this kid of subject would be appreciated.</p>
<p>well, i’m not in college but i do have college professors as teachers and they say that for any class in college, for ever hour of class you should do 3 hours of studying total. so, go by that?</p>
<p>i mean, if you have a class once a week, and it’s an hour 30 minutes then i’d spend 3, 4 hours a week studying its material. hope that helps</p>
