Using a quiz in Presenter 09

I have several quizzes mixed in to a presentation in Articulate Presenter 09. I have it set up to where the user has to answer the quizzes correctly to move to the next slide. Something that is happening, if the user hits submit button then they are forced to answer question correctly before proceeding. However, when the user gets to to final question and if they attempt to answer the question at least once the navigation bar will let the user proceed without answering the question correctly. Is there a way to prevent this? This is happening on 4 different quizzes that I have in the project.
