School talk:Mathematics/Facultative courses
The link to wikipedia turns up nothing for facultative. If you are going to use a term like facultative, you should probably ensure that wikipedia and wikionary both have entries for it. A quick google define: search yields mostly biology terms, but a few things about "optional" at the bottom. I would not presume to provide a definition for the wikis, however, as this is the first time I've ever heard the term.
