it'd be better than what they're doing now but pretty much all unis will put you on probation if you get below a certain GPA for a semester (usually a C or D average), and then expel you if you don't get above that the next semester (unlike public HS, which will make you do counseling but usually can't expel you for failing, you just wont grad)

plus half of the characters wouldn't even go to or get into college. maybe Rue lives with her mom doing nothing but often crashes at Jules'/Lexi's dorm?

maybe they could cast them for their actual ages and play friends/acquaintances/roommates in their mid 20s. i guess there's less structure in that tho
