Report last score for grouped scenarios in quiz

I'm creating a quiz in which the learner has two chances to get the answer correct.  If they get the first opportunity wrong, they are directed to a feedback page then taken to a third slide for a second opportunity to answer correctly.  I need help determining how to achieve the following; if they get opportunity A correct, I want CP to report that score and move them on to the next scenario.  If they get opportunity A wrong, I do not want CP to report the score, move them on to the feedback/opportunity B slides, then report their answer there (whether correct or incorrect). They must score 100% on this quiz, so I need CP to report only the last score for the grouped scenario.

Is this possible?
