Is your purpose to get as high a score as possible or to actually find out her strengths and weaknesses? Because your question reads a lot more like the former, which will not find much favor here.
I don't think that anything is thrown out quickly in the way you seem to be thinking in the WISC - there are timed sections, but the whole subtest is set in front of the child and they have to get through it as fast as possible. It's not a rapid-fire ask-a-question-get-an-answer-ask-another-question section like a timed computer-adaptive test. (aeh is our resident expert here who will correct me if I'm wrong, I hope.)
