For a warden to be assigned to you. The Admiral gives them a file with the information required to graduate you... for what it's worth, I haven't heard of any inmate asking him directly for a file, but he doesn't always listen to requests.

Even if he doesn't respond, you could get a job in the kitchen, maintenance, gym, library, garden or as a lab assistant if you have a scientific bent, if rest on your laurels doesn't suit you.
