WikiQuiz is my proposal to create a free, fully editable multiple choice question - quiz site, on which users could create quizzes and test their knowledge on any area of academia that interests them. Used as an educational tool and as a means to test one's knowledge or grasp of a particular subject.
I truly feel that creating WikiQuiz has enormous potential as an educational tool and could potentially set the standard for online tests in all areas of academia.
If Wikimedia is the effort to give everyone free access to sum of all human knowledge, WikiQuiz will be a means of testing that knowledge.
I currently run the website www.wikiquiz.ie (which is in it's infancy), which demonstrates how this website might work.
