That's actually a good question, and I spent a couple hours thinking about it. To make a long story short, Aurelia plans for Apricot to be a team known for having its shit together. Unfortunately, she may not be too popular for the first couple of weeks, because her methods will be very--let's say "direct".
The first, and probably most reasonable, rule she'll implement is "Perfect Attendance" requirement. That means no sleeping in, no skipping, no missing classes for any reason except those already approved by Beacon Faculty. Failure to follow this rule will be impossible, because Aurelia will enforce it by using every means at her disposal, up to and including tying up a sleeping team member to Noble Steed and dragging them to class in their pajamas/underwear/in the nude. This will also not be a surprise, as she will state that she will drag any attempted offenders to class herself.
However, if class is missed for any reason by any team member, Aurelia will do everything in her power to make sure the class is made up. This will involve a mandatory tutoring session for all APRC members that will take place bright and early on weekends. Yes, all APRC members. "Chains are only as strong as the weakest link" as they say, and Aurelia will not tolerate weak links. Keep in mind that "mandatory" implies the same "impossible to break" mentality as her Perfect Attendance rule.
Now, this brings me to another contender for most reasonable. On weekends, Aurelia will require an hour of your time at a relatively reasonable hour for team training, generally extra sparring practice. Assuming no other infractions, weekends are otherwise free.
That should generally serve as a good preview of Aurelia's temperament as a leader. Overall, her rules aren't really that unreasonable. "Go to class and do satisfactory work." "Team training on weekends." "Keep the room clean, and your things organized." "Maintain personal hygiene." There will only be problems when someone tries to break her rules, because her rules are not made to be broken.
So yeah, go to class, be a reasonable roommate, and perform to Aurelia's satisfaction, and you could get away with murder.
