I don't know whether the test she is doing is timed, but you might see if she understands not to take her time for those parts. Good night sleep, good breakfast, don't let her see that you're nervous (if she notices, tell her you're excited! because this will be fun!) How old is you daughter again?
There may be no basis for it, but I don't let my kids do TV or video before hand. Reading the night before, some fun games that get the brain working like counting by 19s (2s or 3s if she's little).
Good luck! Hope it goes well!
