<p>How old are you? Many times CR scores go up naturally with age. Mine increased 100+ points between 7th and 9th grade without any work.</p>
<p>You might want to look at the types of questions you are missing. If they are mainly from the reading passages, then memorizing words won't do you any good, and either way, that technique only works to an extent. The best advice I can give is to keep taking practice exams, one section per day at a predetermined time. Check your answers afterwards and make sure you know why you missed a question and why the right answer is the right answer. If you can, you might want to find a parent, peer tutor, teacher, etc who can aid you in reexamining your tests.</p>
<p>For the sentence completions, try working one blank at a time, and remember to only eliminate if you are positive that the choice is wrong. Also, look for helpful indicators like semicolons (gives definition) and conjunctions that show tone (and vs. but). Whether or not you fully read or skim the reading passages is a matter of personal preference. I'd rather read thoroughly because I know from experience that I?ll have enough time to finish the test, and it gives a greater sense of confidence when I select an answer. On the other hand, I have friends who stick to skimming, and their scores are none the worse than mine.</p>
