The cached version of course pages shown to logged out users can be badly out-of-date (at least with Chrome in incognito mode or Firefox in private mode, but not while logged out in normal mode with those browsers).

For this course, the out-of-date version has only "Week 1" linked from the "Class pages" section: https://en.wikipedia.org/wiki/Education_Program:Peer_to_Peer_University/Writing_Wikipedia_Articles_(2013_Q2)

Using "View latest" to purge the cache will show the current version, but clicking title again to load the page without the purge parameter will bring back the out-of-date version (which is many days old).
