Survey questions should have a 0 for the point value and should not be editable, according to Stanford test scripts, (Line 116: http://confluence.sakaiproject.org/display/SAM/QA)
Created an assessment with several types of questions and added a Survey type question at the end.
Creating the survey question, the point value is 0 and is not editable.
After saving the question, back on the Questions page, the points box is editable and I changed the 0.0 to 2.0.
Student takes assessment and for the survey question, 2 possible points are displayed.
Student submits assessment.
Instructor views student's submission, and the student received 0.0 out of 2.0.
