accurate curve??

<p>Hi guys, which do u think is the textbook with the most precise and accurate curve. For example, some of my friends told me that on the real SAT their scores were about 100-200 lower than what they had achieved with the Blue Book. Today I took one practice test from the New Barrons ("How to prepare for the NEW SAT 2005") and I felt it was quite difficult...</p>

<p>so, let me have ur opinons :)</p>

<p>someone ??</p>
