Asking a few "school" friends favours?

[Cicero]

So at school I'm friends with a few girls who are apart of the party scene, we're somewhat friends, like we never hangout after school, but we talk a lot when we have the same classes. But I was wondering if I could ask them if they could get me into a party, how would I ask? Even though we've never hung out together, could I still ask?
One of the girls, has let me copy off her homework for math class, and we always talk during art class and what not. And another girl were always really friendly to each other. And another one who I'm starting to chat with.

If you want them to take you, just ask. I doubt they'll have any harsh reaction if you guys are as friendly as you say.
