What's the best SATI prep book for someone who already has a reasonably high score?

<p>I really appreciate your responses. This forum is very supportive.</p>

<p>My daughter did a lot of practice tests since the end of last year. Since she felt more comfortable on Math rather than Verbal, she spent most of her time on Verbal before the March test. She did the Barron's Math IC ( similar to SAT I Math) and Gruber's Math last year and managed to finish the practice tests from CB at many different time slots before March test. I would think she is ready at any time but she always says she needs to review the whole review sessions again. On March 11, she finished craming reading the Math review around 10pm and she could do every problem on the CB book.</p>

<p>On March 12 the actual test, she could do every problems on the two math sessions other than the session with grid in. On that session, there are many problems she could not really understand what it means and so she concluded this must be experimental.</p>

<p>I suspect the questions on the grid in session has some unfamiliar type of questions so I tried to ask people (in other threads) to post questions of the grid in, especially the one with scatter plot. No one responded to that. I can tell these questions which bothered her did not bother other kids at all. That is typical her, who can solve difficult ones but often fail on something very simple and obvious.</p>

<p>How to avoid this from happening again on May test?
I have ordered the questions but CB said it would not arrive before the May 7.</p>

<p>Your opinion, please? Thanks.</p>
