The quiz works very well and is pretty easy to setup. The layout falters a bit if you add images, but you can overcome this in CSS. I would give it a full 5 stars if it worked, or had some fallback layout, for mobile devices - Android, blackberry etc. At the moment it shows all the questions at once, which is fine, but won't let you start - on phones and tablets I mean. Still the best Joomla quiz I've tried though.
