Partial credit/accumulative scoring on branched scenarios


I have created a branched scenario module that should have a maximum score of 30 points. That's the easy part...

There are two main sections which I wish to have a maximum score of 15 points each.

The problem is that on the first question the user can select three options and can score 15pts, 5 points and 0 points depending on their options. However! If the user selects the 5 point or 0 point option they see another set of screens and options where they can still gain some more points.

This continues in the following section.

I can get my results slide to show the total number of points gained but I don't know how or if it is possible to get the overall percentage result to show 100% if the user selects the two best options during the module - can this be done?

Please help!
