Have you checked with her whether she likes you too?
Perhaps she only wants you to be just her "best guy friend" who can
help her solve all her I.T. and English problems. Maybe she expects
you to help out as a friend (and just friend), but from your post,
you apparently do not intend to go that far out as a friend (and
just friend).
Of course, you could make some "accidental" intimate flesh contact
with her for cheap thrills, but if she isn't romantically inclined
towards you, I'd suggest you let her know that while you like her
and enjoy being with her, you are not that dense to enjoy being her
doormat.
