Many features, great flexibility. With the help by ARI-soft I use it with Organic Chemistry plugins in it! Students draw molecules as answer
Ease of use
The extension was were easy to learn, while giving a lot of possibility to prepare your quizzes as you like.
Excellent support and very fast. In 1 day I submitted a request, I received a few answers and at the end of the day, they solved my problem!
The Documentation is very clear, and if something is not for you, you can ask info at the support.
Value for money
Unvaluable.... I rely on it for my Organic Chemistry teaching site. The students love this way to check their knowledge level.
