<p>I have the “Official SAT Study Guide” with 8 full length practice tests and answer keys (but no explanations), and yesterday I purchased the online course that also has 8-9 practice tests definitely with explanations and automated essay scoring. The book’s tests do NOT match up with the online course tests. I purposely signed on for the online course so that we could get explanations for all the questions on all the tests. I don’t know if I have an older version of the printed book or what’s going on. </p>
<p>In any case, the online course is really worth it. Being able to have all sections scored; getting score reports online breaking down every area. There’s a lot of worthwhile “extras” online.</p>
<p>I think I’m going to call CB on Monday and ask where the explanations are for the practices in the printed book, because I can’t find anything that matches these tests online.</p>
