<p>I am preparing for the SAT. My current score is in the 1800s. I have heard that the Princeton Review prep course is excellent, but I've also heard that it's bad and that you shouldn't waste your money. Is it good for beginners and bad for those who are already advanced?</p>
<p>I've also heard very good things about testmasters.</p>
<p>Is there any other course I should know about besides practicing on my own?</p>
