Worse and worse on SAt

<p>So I've taken the sat for the third time this year (my last) and the score I got was significantly lower than I've expected. Ever since I've taken the first sat over a year ago, my scores have been getting lower and lower each time. My second score was about 60 points lower than the first time I took it and the score I received today was 10 points lower than my second score. This is frustrating because I put so much work into the studying for the third test. On practice tests (college board bb and princeton review), I've scored up to the 2300's taking full tests, but the score I just got back is about 250 points lower. This is despite the improvements I've made while studying. Can anyone possible explain this? I'm not especially prone to test anxiety so I don't think it's that.</p>
