<p>okay. So i have the blue book and i am pretty sure its the latest version. But are there many versions? Like different year with different tests? And in the online course, does it provide explanations for the questions in the practice tests in the book... because the book doesnt have any.</p>
<p>No new versions; there is only one blue book. And yes, if you suscribe to the online course you get full explanations to the blue book answers.</p>
