Some of our students require 20% of additional time in order to complete each quiz/exam. For example, if the quiz lasts 20 minutes, they should get extra 4 minutes.
I know about the User/Group Overrides functionality, and it's great, but it's specific to an individual quiz.
Is there any way (maybe with a plugin), to set an extra time (calculated by percentages) for a student in all quizzes, without the need to set the extra time in each quiz?
If this functionality can be applied to the entire system (and not specific to a course), that would be great. I mean something like a student having a perference in his profile page that determines if he is applicable for a an extra time in quizes and how much %, and then the system/plugin applies it to each quiz in each course.
Thanks in advance
