I've created a powerpoint with several quizzes embedded throughout the tutorial. The idea is for students to click through the powerpoint slides, and after every 2-3 slides, they have to answer a question to continue. Each question is contained in its own Presenter quiz. I've created my own customized feedback slide after each question so I have each quiz set to not show scores after each 'quiz'.
I want students to attempt to answer these questions before moving on, so each quiz is set to "Required." However, if you view a question, then go to a previous slide (click the back arrow), and then return to the question (click the forward arrow), the 'next slide' button is enabled and the student can go to the next slide without attempting to answer the question.
