Once your assessment is `Under Review`, you'll be prevented from making changes directly to your answers, and you will see a grey titlebar indicating that. From this point on in the verification process, you will need to make a request for changes to be made to your assessment. To request an answer to be changed, navigate to the Question Filter using the navigation panel on the left.

Even though the questions Answers are read-only, comments can still be made underneath each of your Answers, so that you can clarify your answers, or request and Evaluation Analyst to change an answer.
