Homework/study habits?
Ahsoka: Usually turns her homework in on time. But it's late often enough that no one's surprised.
Anakin: Very good student...in robotics. Everything else? Well, he passed! That's the important part.
Padmé: You don't pass the bar exam at nineteen without good study habits.
Obi-Wan: Smart, but goofed off way too much. Pretty regular grades.
Barriss: Solid student. Well rounded. Everything's done (mostly) on time, and she will do allll the extra credit.
Luminara: It's early. All of it. Everything. She wasn't top of every class for no reason.
Rex: Didn't ever have homework, but if he did, he'd probably be a better student than both of his on pizza?
