Hi Christine!

If you've exhausted the content and are looking to retake the practice tests, currently our best suggestion is to create a new account; this would allow you to start from scratch. 

Alternatively, you could also work through practice problems outside of the practice tests. Our system will then make recommendations on what to focus on, proposing a combination of the skills you need the most practice on and those which are most relevant to the test.

Lastly, we're tracking the off-track messaging as a known issue. Thanks for taking the time to note this, we appreciate it!
