Official SAT Online Course: worth it?

<p>I'm planning on taking the January SAT. I just bought the Official SAT Study Guide (Blue Book).
Should I also pay for the Official SAT Online Course? Has anyone here used it? Is it worth it for the essay grading service?
And I think I saw something on collegeboard.com about a discount for the Online Course if you own the Official SAT Study Guide (Blue Book). Is this true? Are there any other perks for owning the Blue Book?</p>

<p>Thanks.</p>

<p>This is what I found on CollegeBoard. (<a href="https://satonlinecourse.collegeboard.com/login/splashConsumerLogin.jsp%5B/url%5D"&gt;https://satonlinecourse.collegeboard.com/login/splashConsumerLogin.jsp&lt;/a&gt;)&lt;/p>

<p>A $10 discount on the full online course, including auto essay scoring & explanations for the book's 8 tests. </p>

<p>In The Official SAT Study Guide: For the New SAT, what is the last word on page 325? </p>

<p>(not sure if this is different for other people)</p>
