Revised GRE scores vs Old GRE scores?

<p>Hello everyone I have a question that i am sure many people have:</p>

<p>New GRE scores range form 130 - 170, as opposed to old GRE scores that range from 200 - 800</p>

<p>That gives you a range of 40 points (1 increments) vs 60 points (10 increments)</p>

<p>If the scores are proportional then 1 new GRE point = 1.5 old GRE points.</p>

<p>According to that 150 = 500 , 160 = 650 , 170 = 800</p>

<p>The problem is I am not sure you can extrapolate the results as if they where proportional.</p>

<p>I currently took 2 practices test and I scored 159 (635) and 160 (650) but when I take the official practice test which still scores in the old scale i got 750 (164).</p>

<p>I was planning on applying to Berkeley so I had a target score in math of about 750. The problem is that according to new scale I have not idea what score should I get and with the extrapolated score I am getting a much slower score than my target.</p>

<p>If any of you have the same experience and might help me.</p>

<p>Thanks a lot for your time.</p>
