No improvement of my CR Score....

<p>I'm fine with sentence completion sentences, but my problem is that I can't seem to improve on the passage based reading questions. I have been through 6 CR Practice tests from the Blue book so far and I cant seem to improve my score AT ALL...</p>

<p>If I get an answer incorrect, I would go back to the beginning of my answer sheet, cover up all the answers, and try to reanswer it and find out why my new answer is the right answer. If I can't, I look at the answer explanation and I don't move on to the next incorrect answer until I fully understand why I got the problem wrong.</p>

<p>Is there something I should be doing? It's really discouraging to try and improve my CR score when theres barely any days left until the end of Summer and I should go ahead and study Math instead (I get near perfect on Writing already)</p>
