<p>Don’t you get online explanations for the Blue Book tests without course subscription? </p>
<p>Personally, I didn’t finish the Online Course to be of great use… but then again I was stupid and lazy and didn’t really take advantage of the practice quizzes it had. The online course tests are useful practice; the explanation/review sections are almost exactly the same as the blue book. Aside from the additional practice tests, the only thing that sets the online course from the book apart is practice quizzes, which have questions similar to the practice tests.</p>
