Quinn have different "feelings" for Maya and Josy.
Josy it's simpler, she just wants to mess with Tommy, so she decides to let the girl try out for the HOTs to simply annoy him. As someone who likes to troll people i like, i really understand that. I think the only difference is that i would prefer Josy to partner with someone else so she wouldn't be subjected to Maya's list. But that's because i like trolling my friends, not being cruel with them.
Maya is more complicated, because it's not just to mess with her. Quinn knows Maya isn't HOT material, and she is right about that, not only that but i think Quinn can sense how Maya don't really want to be there and like the start of the game shows, has contempt for the HOTs. Honestly, i don't know if Quinn cares about the Sorority ideals or something, but if she does, she may see Maya as some kind of opportunist. Anyway, for Quinn i think the thing with Maya is personal, aside from the sorority stuff there's some jealousy in the middle (the way Quinn calls Maya barbie, she probably sees her as someone who had an easy life) and even some rivalry because Quinn does seem to like the MC.
So, because of all that, at the start i think Maya's list was sink or swim. If she did everything, she would at least prove herself useful to the restaurant and would be accepted into the HOTs, if she couldn't even better because she was a waste of time from the start.
After episode 6, i think MAya should just quit the sorority, if there's one thing Quinn is right about, is that she doesn't fit there, and besides, she doesn't even want to be there or like the girls there. It won't make sense to her to stay there.
