my undergraduate degree was probably 3+ hours / hour of class (programming degree, so there was a lot of programming). My graduate degree was probably 5-10 hours homework per hour of class at a minimum, but it was liberal arts - a LOT of reading (sometimes a number of thick yet interesting tomes per class meeting).
So it really depends on the learning you are wanting, I would think. Something concrete and with a well-defined scope (shooting/maintenance of guns*) may not be too bad, but something more esoteric or less-well defined** (Aslan philosophy of Trading) may take a lot longer.
*this comes from someone with no gun knowledge other than knowing which way the bullet comes out, so I could well be wrong.
**and you can't get more 'less well defined' than a liberal arts degree - it can be anything (in my case, the human condition, and my thesis was the ethical considerations of artificial intelligence. So I blended my BS with my MLA...)
