I was looking at my college grade distributions, and noticed that there are classes where a solid 30% of the people receive a WX. I always though that this is basically the same as an F, and counts for 0 on your GPA. So why in the heck wouldn't you just stay in the class, with the possibility of bringing it up to a D. I might be missing something, could someone please explain. By the way, I'm not in a situation where I have to make this choice, I am simply curious.
