The tag exams has been created on meta. It might be useful, since there were some discussions about possible cheating in exams with the help of MSE.

I've made a suggestion for tag-wiki and tag-excerpt: For questions concerned discussion about using MSE for cheating on exams. (For example take-home-exams.)

If you have an idea how to improve the description of this tag, please do so.

I guess it would be ok to remove the tag (and replace with the more general one, where necessary.)
