Moodle – Default Neutral Vote Option

---

The default moodle neutral vote option is to check a ‘radio button’ “neutral” by default for a given vote. This is not defined in moodle itself, and required a small modification to one of the files. 

This document addresses the change required to be made,

The file to be modified is under
/var/www/moodle/mod/questionnaire/questiontypes/

The file is,
questiontypes.class.php

Depending on the version of moodle, it may be necessary to make modifications to the file in the new location, instead of replacing the file – as new features could have been added. Doing a diff of the backup file and the modified file will give you the changes,
