Princeton review prep exam score

<p>I recently gave a sat preparatory exam with the Princeton Review. I got a guaranteed 2300+ expected score and was pretty happy about. Then I read about people saying that PR prep tests are synthetic and fake and may not show my real score. I get that no one can exactly determine what score I get, and anything might happen on the real Sat Exam. But a good guess will boost my confidence. Please share if anyone has any thoughts or experiences about the accuracy of Princeton Review tests.
Thanks</p>
