<p>I have the first edition with 8 tests and its completely marked up with no explanations online or in the book... Does anyone have explanations for it? Also, i am considering getting the new book, whats the overlap between the editions since i am considering throwing out the first edition since its all marked up, i don't want to lose valuable tests.</p>
<p>All eight tests are in the second book too, I believe. With two new ones (previously administered tests, with the exact curves)</p>
<p>does the 2nd edition come with free explanations in the book or do i have to access it for free online?</p>
<p>Online access</p>

No, the new BB has only 7 tests from the previous BB.</p>
<p>You can access answers and explanations from the new edition of the BB here: <a href=“https://satonlinecourse.collegeboard.com:443/SR/home/bookOwnerArea.do[/url]”>https://satonlinecourse.collegeboard.com:443/SR/home/bookOwnerArea.do</a></p>
