<p>Is the blue book published by the collegeboard outdated? It was published back in 2004. Are there any updated versions of this book or is this the most recent one? And also does it provide explanations to the answers in the tests (either in the book or online)? Thanks</p>
<p>Yes, explanations are provided in the book. I’m not familiar with the online course but I imagine that it does. You might also want to take the free full length test on the College Board site and sign up for SAT question of the day. Both provide explanations.
