At each feedback screen you can determine whether to indicate the student's response is right, wrong, maybe or information. Click on the check mark indicated with the arrow to see the popup that appears below. Then click on the choice you want. Here, Right has been clicked, so this response will be graded as right. For more information about what to include in the feedback boxes, please refer to the FAQs "What sort of information does the student get? And, what type of information should I include in a feedback box" and "What tone of voice should I use in the feedback box."
