Had a request a few weeks ago for timed testing capability in MooTyper and it is now available in this new MooTyper 3.8.2 version. It is a little bit more though, as the time limit works in all three typing modes.
There is also a new required WPM setting that works the same as the required precision setting.
There a number of new cosmetic changes where more information is listed in some of the labels on various pages. There is also a new Cancel button when an admin/teacher/manager clicks on Settings.
You can try out the new capabilities in the course at http://m3x.drachels.com/course/view.php?id=4
