@"Alex Divine" The question is whether LSAC could come up with something even better if they so wished. I'll bet they could. But as long as the law schools are happy with the status quo, there will be little motivation to do so.
Thanks for sharing. Similar phenomenon happened in China. Children were left with their grandparents.One reason is the parents(who works in big cities)' motivation of gaining better economic status and social resources(health care, education) in cities.
