Hi Sarah

The Aiken format only allows the import of multi choice questions whereas the Gift format allows for a wider range of question types.

One way to check the format of the file is to export a quiz from Totara into the Gift format 

Doing this for a multi choice question called test  in course named cert course 3  with two choices Yes and No the format looks like

// question: 0  name: Switch category to $course$/cert course 3

$CATEGORY: $course$/cert course 3

// question: 11  name: test

::test::[html]<p>question?</p>{

=<p>yes</p>

~<p>no</p>

}

Regards
