Wow, as an undergrad who has endured years of stressful schedule twiddling followed by a 2-week sprint to figure out how I'm going to replace all the crap courses I naively selected months ago, that sounds like paradise.
It's not exactly paradise. Because classes are only ten weeks total (slightly less in spring), you can't exactly spend the first week or two shopping around without doing non-trivial work for every single class you're shopping --- an approach which doesn't scale, to say the least. There's still a sprint the first few days. But still, it's nice.
