Excellent Plugin and Support

The Plugin and Pro Version of this quiz system is just excellent. I tried numerous quiz plugins for different requirements. I endet up with watu, it got lots of customization options that make sense. With watu you can create complex exams and gradings.
The support is outstanding, a question is answered within ours. The plugin is regularly updated and the creators even helped me to customize a part of the code for my needs.
Thanks and keep up the good work!
