The form code at the bottom does not contain the answers in any way. Those are for letting GradeCam know if it is a specific student or assignment so a teacher does not have to open an assignment to scan the forms. We have many ways to create our forms, and one of them is to have the form be specific for a student for a specific assignment in their class. This is what is embedded in the form code so GradeCam knows where to put the student's score.
I hope this alleviates you concern. If you have any other questions, please reach out.
