Tolerance settings (if available for your book title) allow you to set the variance in acceptable answers by your students. Setting tolerances allows a wider range of answers to be scored as correct. You can also customize the tolerance setting, applying different settings to different course sections.
To set answer tolerances, select an assignment from the Section Home page. Click the policies tab (A) and then click view & edit policies (B).
Click advanced settings (A) and then select edit next to (B) tolerance (C).
Depending on your assignment, you can set language (A) or numeric (B) answer tolerances. Once you’ve made your edits, choose whether to save as default settings or apply these changes to this assignment only (C).
