It's also you need a team (or a PM or two w/ the ability to pull tech resources) of people that are focused on MCAT. Anytime you just leave something static as an org it will rot away in usefulness very quickly.
So just hide it, and put up a warning message at the top that the course is no longer updated. Why do they need to take it down? It won't consume bandwidth unless people actually use it (in which case, they must find it useful), and I can't imagine raw disk space is a concern. Or, if it is, throw up a torrent so at least people can grab the data.
