Go to her house at night, throw a stone at her window to wake her up, and when she sticks her head out, start declaring!

Ask her does she got time to do homework with you in somewhere then confess to her when there have no one there, If she go with you for whatever reasons and which mean she is on the way Leave it if she say no by thousand of excuse.

eh? At least try to write some details ... =)

I don't understand what you are saying.

I depends how you like this girl and what your trying to tell her or declare :)
