Hi,
I need to create a questions bank for rotative quiz, any ideas which app can do?
Why not create your own ?
All you need is…
- a DATABASE with questions and answers.
- a Multistate-Box (can also be maden with other elements)
- some control-elements (Buttons/DropDowns/Sliders/Checkboxes and so on…)
- and of course —> CODE which will let running all the quiz-system.
A first look at what i am talking about, you will find here at this example…
