In order for you to manage your questions and tests in the "my library" menu, you have the "Archive" or "Remove" features.

To "remove" just go to "my library", search for the question you want and in the right side menu click on the trash can icon. For the button to be enabled, the evaluation must not yet have been answered by any candidate.

You'll also find the remove option when viewing a test.

To "archive" an evaluation, just search for the desired evaluation in "my library" and click on the box icon in the right side menu, it will go to the "Archived" tab in your library.

NOTE.: You can only archive a review when it already has responses.

The archive option is for you to save your questions that are not currently being used. You can consult these questions in the "archived" menu
