Practice Tests vs Actual SAT and SAT book advice

<p>Hi all. I need some help. So in the months before the March SAT I was studying a lot. I took practice tests (from collegeboard) every week and scored relatively well on all of them. My range was 2050-2160 on them so I was planning on scoring the same on the actual SAT. Anyways, March 8th came up, and I was ready to ace the test. After the test, I felt I did alright, but I knew Critical Reading didn't go that well, and I felt that I had made quite a few Math mistakes. I got my results yesterday, and I am still stunned. </p>

<p>CR- 450 (450?! I won't accept that. I haven't scored that low since my VERY FIRST DIAGNOSTIC SAT. I usually score around 600 on my practice tests.)</p>

<p>Math - 600 (This severely ticked me off, because I usually score around 710-780 on my practice tests.)</p>

<p>Writing - 620 ( This also severely ticked me off because writing is my best subject. I usually score 750-800 on writing.)</p>

<p>Total score:1670
This score is not at all my standard, and it is sure as heck not where I want to be. I have no idea what happened on this test. My full online score report comes on April 1st so I'll look back and see what happened. Hopefully my score isn't an April Fools joke.</p>

<p>I've started planning and I'm going to retake it on June 7th, but I also need advice on books. I already have the blue book, by the way. Oh, and my school got the SAT online course for students so we don't pay a dime. </p>

<p>So far, I've decided on getting the following:</p>

<p>Barron's SAT Math Workbook
Barron's SAT Critical Reading Workbook
Barron's SAT 2400</p>

<p>I really need advice on these. I want to score a 2200 or above. Yes, that seems pretty far, if you look at my March SAT score, but I know darn well that that is not my level. Anyways, thanks for helping and I appreciate all your responses.</p>
