Quiz: Adjusting or Curving a Quiz Grade

Moodle ISU


Introduction

The quiz function in Moodle ISU allows instructors to set a question’s worth within the activity. Changing this worth after the quiz has already been attempted is known as curving the grade. Reasons for changing a question’s worth after the quiz has already been attempted include, but is not limited to: the question being worded wrong, the correct answer being wrong, too many people missed the question and you wish to scrap it altogether, etc.

Add Extra Credit to a Quiz

  1. In the Administration block, Click Gradebook setup.

  1. Scroll to the bottom of the page.
  1. Click Add category.
