I was working with offline quizzes (pen-paper based exams). For that I used this plugin:
https://moodle.org/plugins/mod_offlinequiz
This plugin lets you create a quiz and then provides downloadable PDF/DOC answer form, question paper and correction form. The answer form is where you mark your answers.
The answer form has squares. So to attempt a question, you have to put a cross (X) in the square against the respective option for respective questions. If any other marking is done, it will not be accepted. Once done, you then have to scan these answer forms and upload to your moodle instance and they get corrected and you are provided with the results.
Now what I want to achieve is instead of squares, I want to scan for bubbles (circles) and consider a completely filled bubble as a valid attempt. So is there anyone who has worked with the plugin or has any solution/way to do this?
