PSAT scores.. Accurate?

<p>So I just took a full PSAT practice test from the 2010 PSAT Practice booklet by the College Board that I had found online and my results were as followed:</p>

<p>Writing-70 (3 errors)
Math - 69 (3 grid-in errors and 1 MC error)
Critical Reading - 56 ( 15 errors :_( I suck at it )
Overall-195</p>

<p>What I would like to know is whether or not if the 2010 practice booklet were accurate?</p>

<p>BTW I'm a sophomore and I got a 164(64M 50W 50 CR) on my PSAT that I had taken in OCtober 2012.</p>
