How do I create a question group that allows the students to choose which questions they will answer. Example: I want students to answer 2 of 3 essay questions. When I created the question group and entered the instructions to answer 2 questions worth 5 points each, the system only shows the students two of those three questions. I want to set this up so that the students see all three questions and then select the two that they want to answer. I don't see a way to make all three choices visible to the students.
