Customer Query: How often can I review each of my answers after I complete a test?

We recently responded to a customer query regarding how often saved sessions were available for review and we responded with the following:

You can review your completed and saved sessions with all your answers and corresponding questions & explanations as often as you would like. Your access codes will never expire. They are valid indefinitely. Any of your saved results will be tied to your redeemed access code and can therefore be reviewed indefinitely.
