You can print an assessment with or without an Answer Key.

Note: Certain types of questions may not display exactly the same way in a printout as they do for a student taking a test.  For example, if you have any Calculated Questions in your assessment, they will not display numerical values in a printout, because a single Calculated Question can contain different numbers for each student based on the variables entered.  Instead, you'll see a formula, e.g. {x} + {y} = {z}.

A question pool is a set of questions of any type that belongs to the author and others with whom the author shares it.  See What is a Question Pool?

You can import a question pool from a saved assessment, or from an IMS QTI-compliant XML (QTI v 1.2) file provided by a publisher or exported from another system.

To be able to import questions directly into a question pool, an assessment must have been exported as QTI v 1.2, NOT Content Packaging.  Alternatively, you can import an assessment, and add the questions to a question pool from the assessment editing screen.

Note: There is currently no way to export question pools, but the questions can be exported in the form of an assessment.
