<p>Does this really help? I mean, I'm buying it soon but I wanted to get it after being exposed to some opinions. I'm only buying this because I have completed all of the tests in the blue book and I still need more practice. If you've taken the course, please tell me if it actually helped and how much you improved by. I'm not planning on taking into count any advice the college board gives, I just plan on using it for the tests and quizzes. I need to improve by 250 points by October to reach 2100. Thank you. </p>
<p>Also, does it hurt to take the practice tests online rather than on paper?</p>
