<p>For the different editions of the official study guide made by College Board, do they have different practice tests from one another? or are they the same?
And i saw the two official study guides made by College Board in the book store; one has CD, while the other one does not. Do they have the same tests?? Than you ^^</p>
They are exactly the same. The difference is that the CD has an extra test, so tie worth buying it. In amazon it’s just a 2 dollars difference.
