How to sort participants by best or worst score
To start, click on the activity you've created in your course.
Then click on the evaluation phase you wish to view.
On the left-hand side of the score distribution, you can view the participants' overall average or the average for each criterion, by selecting either Average score or Criteria average score from the drop-down list.
On the right-hand side, you can view the participants' ranking and sort by Best answers, Worst answers.
If you wish to sort by a specific criterion, select the Criteria average score view and click on the criterion; the ranking on the right will be updated according to the scores received on that criterion.
You have a second option for sorting participants by directly consulting the Detail table with the list of all participants and clicking on the table headers to sort them on the phase and value you wish.
