I have tried to create my own feedback master. I have deleted content on the master and layouts. I have inserted by new content. When I create a new quiz slide not only is my new content in the feedback e.g. correct but articulate inserts everything I thought I had deleted. I searched through the posts and the only thing I have found is to move the original off the slide. Surely there is another way of taking out the default content.
I look forward to any response.
