Yes, it does.
I quite like the ease and simplicity of it, and there are some advantages over others I've tried.
It has a significant advantage to the one (JibuPro) I currently use; in JP the content provided by shortcode isn't indexable by the Relevanssi search plugin and hence isn't returned in results, whereas in WPQuiz it is. I think the admin is easier too.
I haven't yet looked at the code to see how easily it might be adapted to include additional features, and wonder how keen you are to expand it?
The facility to show a 'done... you correctly answered x of y questions' message will be very useful.
