How reliable is the official SAT MATH II study guide?

[shootastar]

<p>I just did a level 2 practice test in the official sat math study guide and scored 790. It was so much easier than Barron's. </p>

<p>Can anyone who has taken the actual sat math ii test verify whether it is of the same level as those in the official study guide? Thanks!</p>

<p>Barron’s generally designs their tests to be considerably harder than actual exams, such as those found in the study guide. The study guide exams will generally be closest to the correct level of difficulty.</p>
