Which books should I read?

<p>I just gave the SAT practice test.
M 800, CR 600, W 680 (Total 2080)
Right now I’m in 10th grade, and I believe I have no reason to worry in Mathematics, but I am really worried about my CR and W sections. What books should I read/solve to improve my scores in those parts(especially the passage and vocabulary)? Also, (this may be a n00b kind of question) why is there no section 4 in the question paper(I used the pdf version).</p>

<p>P.S. I gave this test without any prior preparation, so I’m still happy with my scores :)</p>
