Having Trouble with Individual Quizzes and the Final outcome of the 3 quizzes combined

I need help!  I have 3 individual quizzes of which I created variables.  When the result is generated for each quiz, it shows a total of 100 % even when 50% is wrong.

After going through the scene, answering all the quizzes the final total that combines the 3 doesn't reflect correctly.  I have recreated each quiz result and even the final; the outcome still comes out incorrectly.

How can I fix this?  Attached are screen shots of my setup with Quiz 1 and final.  Quiz 2 & 3 are set up the same way.
