Actually I am using this plugin since 2013, So I have explored all the features as well as developed few new feature listed below
1. Negative Marking feature.
2. Fractional Marking Feature.
3. Bulk Marks assign to all/selected questions inside a quiz.
4. Clear answer button.
5. Advanced layout for desktop.
6. Student Profile Page.
7. Exam History for the attempted quiz with result.
and still working on to improve this plugin.

Hello fantoan, currently limit to show number of questions is there but it’s not based on the categories.
This feature is in our list and we will start working on it as soon as we complete the student profile page to show the details of attempted tests and bulk question upload from MS word file.

Hello I have checked it and it’s not working in your site. There may be problem in permissions.

Use single choice and in options select the correct answer.
Add category to the questions as well as activate the category wise result in the results section.

Hello first you have to create the category for quizzes, category for questions and quiz template.

Here the flow is create quiz –add questions — copy short code and publish it via post/page.

Well if I say frankly I am bit confused with your question so here I am telling you the all available ways to duplicate a quiz inside Wp Pro Quiz.
1. If you want to duplicate entire quiz means with questions then first export that quiz and then import the downloaded file. It will duplicate the same quiz with new shortcode. Now you can edit the Quiz name and other details.

2. If you just want to use the same Quiz Description again and again then you can make/save the template from bottom of the edit quiz option. This will help you if you are using same criteria like – timing, result variables,

3. If you want to use the same questions inside a quiz to the another quiz then you can use the copy questions after adding a new quiz.

I hope these ways may help you.

To achive this you have to customize the plugin.
