On the quiz results screen, you (students) can also request an answer explanation.

You should make a request if 
  1. you don't understand the existing answer explanation
  2. there isn't already an explanation
  3. you think the question is wrong and needs to be rewritten. 

Your request will get sent to a) your teacher on Piqosity (if applicable) and b) all educators associated with the subject you're practicing.

Once your request or flag has been answered or addressed, you'll receive a notification via e-mail and on your student dashboard in the "Alerts" view.

Note that the image below refers to a "flag" button, which has since been removed.
