<p>my current real sat scores are 1670 ( 490 c , 590 w , 620 m ) </p>
<p>but after practicing my score increases from 1670 to 1800---->1900 </p>
<p>Math from macgrawhill 710 and in real 680 to 710 ( just silly mistakes impede me from acing math and iam working on it )</p>
<p>writing from macgrawhill 650 ( essay 8 just like that of the real test ) but is maccgrawhill harder in writing than the real sat test ) ??</p>
<p>It is difficult to compare scores from McGrawHill(or any other non-official SAT source) with real SAT scores. If possible please take full length practice tests that are previously administered Official SAT tests. The blue book is a good place to start.</p>
<p>I question is should I deduct 200 points from my scores in home if I got 2000 in home this means that I would get 1800 in the real test</p>
<p>It is really hard to know what the proper way to convert the scores from McGraw Hill to the real SAT would be. The best bet would be to take the real tests that have a proper scale and conversion.</p>
<p>@satquantum yesterday i solved one real test and i got in it 1900 ( as i know that when my mark in home is 1900 this means that in may it will be 1700 ( -200 from my score in home it that right ) </p>
<p>As long as you did the entire test in one sitting, just like the real exam, then the 1900 is an accurate assessment of where you stand. If you want to add the additional pressure of being in a test center, then perhaps go to a library or a quiet place to take the test. But certainly taking the test at home adds to the comfort. I wouldn’t subtract the 200 to gauge your real SAT score. </p>
