If you have been given permission to edit a question bank by your peer, you will be able to make changes. Here are the steps on how to do so.
Click the menu icon on the top-left of the screen, and then select Resources.
If the question bank has been shared with you directly, you will find it within the Shared with Me tab on the left sidebar.
If the Question Bank is shared with a group you are in, then select the group to which it has been shared.
Note: As a default, you will view all types of resources upon selecting a tab on the left. In order to filter your resources further, select the Question Banks tab on the top, or search by the name of the Question Bank in the search box.
Click the question bank you would like to edit.
Click the Edit button on the right sidebar.
Note: If you do not see this option, it means that you have not been given permission to edit this question bank. Editing permissions can only be set by the creator of the question bank.
