<p>Bear in mind that not all majors are of equal difficulty. It’s possible that these graduation rates are deflated by majors which either have a large number of requirements, or else include some courses which are very difficult or something like that. Just guesses, though, I don’t have any numbers to back that up–it sounds reasonable, though. As for whether good GPAs are hard to come by, I don’t really know–I’m just a frosh, so I haven’t had anything on real grades yet.</p>
