How to prevent scores from reporting to the LMS?

I am working on a module for two different groups. Each group has a set of questions that need to be answered. Since I can only apply one test to the module the total score that is reported to the LMS is not a complete score. I am using Sumtotal LMS. I decided not to show the final score and just to give each user a passing credit for completing his/her portion. I kept the Success criteria and the interaction reporting data unchecked. However, the LMS still register the final score.

Is there anyway with some action script or JS I can do to prevent the score reporting?
