<p>Is there a collegeboard explanation guide to this first edition online?</p>
<p>Although I am not certain, I believe that most of the tests are identical, so you can use the explanations for the second edition.</p>
<p>^ there is no explanations for BB questions, even in 2nd edition.</p>
<p>yes their is
go on the collegeboard website and look for them, they only have answers to the second edition.However the second editions 4-7 tests are the same as the first blue book’s 2-8 tests.</p>
