I'll find out soon enough (hopefully) but if I left Mining 4 learning at the close of the last testing day, and it counted down and says I have learned it, have I really? or will it go back to the last time remaining when the server was closed?
Yes! Always leave your longest skill going at the end of a test. The ability to change skills actually ends a bit sooner than the test does, usually by about ten minutes, so it's a good idea to switch skills fifteen minutes or so before the announced end of the test, or a bit sooner.
I guess that means the down time is not a complete loss... now if that "closed" sign would just go away, i can get down to doing some serious glitching =)
