<p>I have the first edition, it has 8 practice tests. However, I just accessed the Book Owners' Area of the CB website, and it has answers and explanations for the 10 practice tests in the 2nd edition. Is there any way for me find answers/explanations for the book I have, or do I have to buy the latest one?</p>
<p>7 of the 8 from your book (the one I have too) make up 7 of the 10 tests from the 2nd edition. Poke around until you are able to match up the tests.</p>
