kapusta: Try telling her that as her freind you think she should really focus on passing the AP’s as she has taken courses over the entire year preparing for them and it will greatly reduce the amount of time she will need to spend in college (if she ends up going). And she can always talkto you over the phone or when she gets back from wherever shes going you can hang out, but the chance to pass the AP’s isnt going to come up again.
If you end up going and you dont want to go alone make sure to invite other people along with you, and if she says she wants to do it alone say your sorry but you already invited other people to join you two.
