Response Types include: In-Range Responses, Invalid or Out-of-Range Responses and Last Chance Responses. An In-Range Response is any one of the Response Choices defined for the Question, e.g., if a Multiple Choice Question had four lettered Response Choices, then A, B, C, or D would be a valid, In-Range Response. Using the same example, F would be an Invalid or Out-of-Range Response. An Invalid Response could also be a Response that wasn't appropriate for the Question Type. For example, C or 3 would be an Invalid Response to a True/False Question Type, where T and F or 1 and 2 are valid Responses. The Last Chance Response is the final transmission PRS will accept for the Question. The number of Chances is set in the New Lesson profile.
