Two ways: 1) Chat her up a bit and ask her if she can come over after school to study with you (or help you with something, or help her with something). 2) Ask your grandparents if you can invite her for diner and then do that. If she can not do either, then tell then that you invited her, but that she could not make it, but that they can meet her on the night of the event.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
