Princeton review SAT ultimate 30-hour liveonline course worth it?

<p>My daughter has the Collegeboard SAT book, she practiced on her own and reviewed terms on her own but only got a 1640. She is planning to apply to Columbia, Berkeley, Cornell, etc.. pretty hard schools to get into and we are willing to pay the 1000.00 price tag that goes along with the PR course. Does anyone have any feedback or comments about this course and its effectiveness? Thank you </p>
