If it has no relation to your "Job", why the heck did they give you this "Test"? Unless it was a means to see how well you are able to learn in a short period of time, i doubt it would serve any purpose whatsoever to boost your skill.
I highly doubt the team would give you access to any model they make until they release it, so my advise would be use the time to learn and pass the test, so you can keep doing what you want to do.
Edit: Also, why you would want to continue working for people who give you random tasks that having nothing to do with your work is beyond me. Ask them, reason with them, if there's still no working between you and them, leave, it'll work out better for you. Hopefully.
