Adjust scoring tolerances

You can adjust the scoring tolerances, or the range of acceptable values, for individual questions. For example, you might want to allow a range of answers for questions that require rounding.

You also can award partial credit for unsimplified answers and set the number of tries for parts of a question.

To apply these settings to multiple questions, see Change settings for multiple questions in an assignment

  1. In the Assignment Manager, select the 3-dot Options menu and choose Edit.
  2. On step 2 of the wizard, select a question number from the Available Questions or My Selections.
  3. In the preview player, select Scoring options next to the question points.

You can:

  • Select use an absolute tolerance and choose a level from the list.
  • Select use a percentage tolerance and enter a percentage in the box.

The sample box shows the effect of your choice.

Set the number of tries that students are allowed for each part of a question without affecting the number of attempts per question. By default, students get three tries to answer an individual version of a question before the answer shows (except for multiple choice questions with a limited number of choices).

By default, students can make an unlimited number of attempts at a new version of a question with different values. To set the number of attempts, go to step 3 of the assignment wizard.
