Hi!
Perhaps setting up something like this:
For each quiz name its a category - so the admin would create the category.
Each question would be an article in that category - defined by a question content type.
You might have to define different types of articles depending on the question type (true/false or multiple choice). Or maybe using a simple select (true/false) or multiple choices.
Displaying the quiz would be a search type to display the articles in the quiz category.
But now the tricky part is having the controls on article unless there is a module or some java script.
There is something similar in the Front End Managers... In your case, you would need the buttons to change based on the content type - only show 2 for true/false, 4 for multiple choice... Unless there is a way to display a simple select in the list.
In the search type list, there is a JGrid option in the Typography and one of the options is form - not sure if something could be done with that. But there is also a check box. So maybe it would make sense to have check boxes - and each column is the answer column.
I think you would need to be a java script which queries the question id and the selected answers.
Then below the quiz a module submission form which submits the questions and answers in a text format...
Maybe its a possibility???
