anyone else use petersons?

<p>D is taking 6/7 SAT and did the petersons prep course She was really looking to bring up her Math scores by 40+. Anyway in the math pretest she scored 10 points higer than on her first math go around. On the CR she scored 10pts lower than the first time and on the Writng section she scored 60 points higher.</p>

<p>Any idea how petersons stacks up to the real thing?</p>
