How realistic are GRE practice tests scores to the real thing?

<p>I've taken four GRE practice tests and the scores are all in the same range, but is it a true indicator of how I'm gonna do on the real test? (The grad programs I'm applying to only want the verbal section).</p>

<p>Here are my verbal stats:
ETS-140
Princeton-143
Princeton-148 (don't know how that happened, it was the same test as the first and I didn't remember much)
Kaplan-143</p>

<p>The average score for any section is 150...and I'm a little scared that I'm not gonna get into any of my schools with the scores that I've been getting. And I've been studying A LOT, since August.</p>

<p>But back to my question: Are scores on GRE practice tests predictors of what I'm gonna get on the real test?</p>
