I went through the Princeton Review many years ago and it improved my score by about 200 points. Maybe I'm an outlier, but I can tell you this: nobody would pay for or go through the course if the expected boost was 20 points. On the other hand, if I hadn't taken the Princeton Review, I'd have done something else to prep. And who knows how much I'd have been able to improve on my own.
