<p>Also, when you are working on the practice tests don’t worry about time or the overall grade. My daughters always scored higher on the real test than on the practice test. I think they are designed that way so that no one has an unpleasant shock when they take the real test. After you have practiced a while then take one for time and apply Xiggi’s method. If your 520 means that you missed about 18 out of the 54 questions, cutting to 9 errors should bring ou into the mid 600s without a lot of effort.</p>
