I suggest (and Gypsy Spellweaver agrees -- it came from him, actually), that the tag should probably be "exams" a plural form to match other tags here. The other tag (say, tests) should be a synonym for "exams". All existing questions (15 currently) should be made to reflect the change.
Making it "exams" rather than "tests" makes it clear that the tag isn't about software testing, but about evaluation of students.
Moderator intervention is needed since "exams" can't be created by an ordinary user as it is "too close" to the existing tag.
