Different Final for each audience in branched project

Hello all,

Brief overview: I am currently working on a project that branches to show different slides and/or full chapters depending on whether the student is from Canada or US.  The branching decides which route to take depending on a variable set for each country. This all works fine.

The Problem: Each country has a separate final.  Storyline's default publish settings only allow for one Result slide to be tracked.  

Is there a way to set things up so each country will see there respective final exam?  I did not see options on an exam to allow different questions to appear based on a variable... and if you separate the two finals and send them both to the same result slide, a perfect score registers as 50%... 

Any ideas are greatly appreciated.

Thank you,

John
