As a student in a face-to-face exam, if I have made a mistake in my exam response and I need help to undo it, I can raise my hand and receive assistance. This is difficult to replicate online. If EchoExam could provide a method whereby I could capture my issue for my instructor while I am taking the exam, that would be helpful. As an example, if I have answered Question 3 and moved on, but realised later that I made a mistake, I'd like to be able to note that for my instructor to review while they are marking the exam.
