Hello, I didn't find any attached docs you mentioned in your project brief. But I can create the well-formed Moodle XML file which you can import on your Moodle installation. I can create a sample file for you as an assurance that I can do this task before you award me the project.
To do this task I need the quiz question and answer documents you mentioned in your brief and I also need a few details from you as well like the name of the category in which you'd like to import these questions, the format of these questions, I mean whether they are multiple-choice with a single correct answer or multiple correct answers, numerical or essay questions. Grading for these questions. Type of feedback etc.
If you would like to discuss your project with me then feel free to contact me by sending a message even when I'm offline. I typically respond within a few minutes when online and within a few hours when offline.
