Great questions! If you request to change your surveys, and are able to do so, your spot will not change in the queue. You will be able to request a redo for a specific survey. That survey should open up with all your previous answers and you can change the answers that need to be redone. As I mentioned before we do not encourage changing answers to the surveys, and that is why you must request a redo and we will assess what needs to be changed.
Thank you for your support!
