Paulina doesn't want anyone to know, but she's acing her Spanish class. Certainly it has everything to do with her Latina heritage and nothing to do with the class itself, but she's still not one to tell others about it.
Dash won't tell anyone about his study sessions with Jazz. At first it was just because he liked her and thought she was cute, but she made her feelings clear soon enough. He still goes, though, because now he actually has a genuine interest in math and science.
Kwan secretly loves poetry. Not gothic poetry, of course, but anything that strikes him at the time. He can usually get by English class writing B-average papers on poems as well.
Star feels left out, occasionally. She would tell any incoming freshman to stay out of the A-Listers club, if they could. It's not all it's cracked up to be. She has to dress like this and act like that, and she isn't allowed to participate in the theater classes she desperately wants to take. (She goes to them anyway, she just never performs anymore.)
And Valerie? Valerie is glad she got kicked out, looking back now. She deserved better than that; people who were true to themselves and looked beyond the exterior to who a person was.
The A-Listers are an illusion, a façade. After all, their beauty is really only skin deep.
