Old Official SAT Study Guide Book Explanations

<p>So I'm using the 1st edition of the Official SAT Study Guide and I just did Section 5 (Critical Reading) of Practice Test 2, but I can't find the explanations to it. The College Board website only has the explanations to the stuff on the 2nd edition. Are there any free online ways to get the explanations? Thanks in advance!</p>

<p>Khan Academy has an SAT section where they go through the math section. They use the 1st edition. As for the English portion, I have no idea.</p>

<p>I was actually looking for Critical Reading, but I will probably be doing math problems from this book, so thanks a lot!</p>
