Test I am making has two parts. Can this be done?

This plugin is very good. I am using it to create tests. I am attempting to create a single test that has two distinct parts. I would like to know if this can be done.

First, the two part test would be used to assist in a single outcome for one psychological disorder. In the first part there are 12 questions. There are four answers to each question which are rankings of how much a person has been suffering from a certain feature of the disorder. (none at all, A little bit, somewhat and all the time). There are four scales. (None, Mild, Moderate, Severe). The results are the same as the scales. The functions for the results are ranges of scores like none >=0 none<=7 mild >=8 mild =<14 etc. The second part of the test is pretty much the same thing. The diagnosis requires that both parts are present. This is where I am having an issue on how to format the exam.

1) If I create 8 scales/results that are alike so that the first set of questions only gives results in the first set of scales and the second part only gives results in the second set of scales would I be able to format the second half of the test to produce another set of results?

2)If I create the functions so that the results are the same as the first set, i.e. none2 >=0 none2<=7 mild2 >=8 mild2 =<14 etc, would these results conflict? How would I format these functions so that I can end up with what I want? My idea would be to create results that are alike but not the same such as none2, mild2, etc. and the second set of scales would also be none2 mild2 etc.

3)Would this work or is this possible? Thanks for any advice.
