Regarding the quiz component, I have tested other free and paid quiz components before using Community Quiz component. No component satisfied my requirement. Some lacks some features and some lacks some.
Finally, I implemented Community Quiz in my Educational Site and in my school intranet. Till then, I am not getting any problem. Its running smoothly and fast. This quiz component has all features which make it a perfect component both for administrator and end user.
Other beauty of this component is front-end user(registered) can create their own quizzes within a fly. And other thing, Maverick will never give any chance to his clients of grievances.
Once installed, no one is needed to teach how to use it. Everything is clearly defined.
So when anyone thinks of quiz site, I think no other component performs better than this one. Anyone can get 100% value of their price.
At last but not the least, I would like to thank whole Community Quiz team for their wonderful effort for making this a #1 quiz component for Joomla Platform.
