Powerprep II question & quantitative scoring question :D

<p>So I took the powerprep II practice GRE test from ETS. Got 800 on math and 550 - 600 range on verbal.</p>

<p>I have two questions:</p>

<p>1.) Is there only one practice test in powerprep II, or are there more?</p>

<p>2.) Let's say I make a dumb mistake and get one wrong on the quantitative part. on an average year, what would be my score (back to the old gre scoring system of 800max)?</p>

<p>thanks in advance!</p>
