<p>I don’t know if reading constantly is a requirement; surely it helps, but I don’t read that much, and I got an 800 CR (and it was the easiest section for me). I read a lot of articles and such online, though, so that could have helped. </p>
<p>Practicing with real SATs helped me the most. My strategy was to always eliminate the clearly-wrong choices and pick an answer quickly. There were 1-3 questions per test that I had to really think about (i.e. not choose an answer quickly). For those, I just re-read the cited text until I fully grasped the idea that was being tested. </p>
<p>Also, I wouldn’t say that I read very quickly. But I did use the strategy to mark the lines that the questions cited in the passage, and it turned out to be the best approach for me. I could read at a medium pace and answer the questions as I read through the passage.</p>
