How do you use the curve in the SAT BB?

<p>I finished a practice test and was wondering how you use the range given at the end. It says that if you get 9 wrong, or 40 right, you get a score between 640-740. What is that supposed to mean? The range is so big. Do I have to average it out to get a good prediction of my score? In addition, if I do do that, isn't that way off because the curve given for the first 3 SAT practice tests listed 43 right (+ or -1) PLUS at least a 10 on the essay to even get a 700. I mean, wouldn't it be too easy if you can get 9 wrong and (assuming you do average the max and min of the range) and still be able to get a 690?</p>

<p>The BB curve is not at all reliable. I’m sorry… it’s really disappointing but that’s the case. Yes, you could take the average of the two values and that would probably the best you can do given the situation.</p>

<p>In the long run, however, don’t worry too much about scores just yet. Do your practice tests, work hard, take the exam, and then see what happens. No need to waste energy and thoughts for estimating scores for a test you have not yet taken. </p>

<p>Good luck and don’t worry too much!</p>
