<p>I read in College Board that from 2011, the test will not score the wrong M.C. answers. This means that contents in prep books will also be changed. I already bought prep books, but do I have to purchase new ones in 2011 since the M.C. rule is changed?</p>
<p>not much in the prep books will change. They will probably only change “Don’t make any guesses!” to “Make guesses!” And i think you can score the practice tests yourself.</p>
