I have a moodle site running on Moodle 3.1
I want Quiz as per demo link (see below).
You have to create new moodle plugin. Working of new plugin must be 100% as per demo link.
I also have payment gateway integrated into it. So you have to make sure that your code doesnt conflict with any of existing plugins.

Demo link: [login to view URL]@@M163
You can check screenshots on how the final quiz should look like.
