Graded or Survey Question???

New user.  I have a paper survey questionnaire which I would like to convert to Quizmaker for obvious distribution and data collection efficiencies.  This is a investment risk questionnaire. Each question may allow for a single response, and here's the catch ... each response may have a different score or weighting which will contribute towards a sum total for the overall questionnaire.

The fact there is no right or wrong answer would lead me to believe this should be a survey, the fact that each response has a numerical value suggests it should be graded.  I've looked at both and looked at different questions and note that 1. as a graded question I can't set up grading with a different numerical "grade" dependent on the response (ie question with multiple right answers and not have to indicate all to continue), or 2. as a survey cannot attrubute any numerical weight to any question.

An example of a question responses might be :

Strongly Agree       20 pts

Agree                       15 pts

Disagree                 10 pts

Strongly Disagree   5 pts

Any suggestions would be appreciated
