<p>In the middle of June, I believe in the second week, I went online and printed out a Peterson's PSAT practice test, Practice Test 1 that is located on the link at the bottom, and I received a 218, with an 80 on Math, a 69 on CR, and a 69 on Writing. About a week ago, I took another practice test on Barron's PSAT/NMSQT 14th Edition, it was the Diagnostic Test, and I received a 202 about, with a 71 on Math, 70 on CR, and 61 on Writing. It was a bad day for writing and math for me. Then I took The 2008 PSAT Wednesday book, and received only a 201, with a 68 on Math, 65 on CR, and a 68 for Writing. Terrible math day. So anyways, I've noticed my scores have been fluctuating, until just tonight, I finished the 2008 PSAT Official Guide full-practice test from the College Board, and I received a 226, with a 73 on Math, 78 on CR, and a 75 on Writing [I don't think they put the curve on this test, since it's just their explanation guidebook type of thing]. Is this normal, and how come I scored so much higher on one Collegeboard Test and so much lower on the other CB one? And I know Peterson's and Barron's aren't official and their scores are just guesstimates, but I'm really curious as to why the fluctuation is between 20 points. Also, my writing should be in the mid to higher 700's on the real SAT, since I always get in the 10-12 range for my Essay. Thanks!</p>
<p>You should look over the two CollegeBoard tests and see which questions you got wrong. Maybe they just had more questions about a certain grammar rule on one test than on another, or you were having an off day on one of the tests.</p>
<p>I do not have a copy of the 2008 Official Student Guide but I do have the 2007. The 2007 contained the PSAT administered on Wednesday 2005. Most likely the 2008 is identical, or at least contains a previously administered test, and thus the curve is accurate. I would only pay attention to the CollegeBoard tests to try to predict what kind of score you will get. It sounds like you are on track for a good score on the real thing. My advice is to stick with real tests, use SAT tests if PSATs are not available and save the real PSATs to predict your score as the time draws closer.</p>
<p>Yeah. I already used 1 free practice test, and then the Guidebook, so I still have 4 old tests. I also have 10RS, 8RS, Blue Book, and I’m going to get the 2nd Edition BB, isn’t that exciting how it’s coming out in a few weeks? Anyways, I’m gonna hold on to them and then just get the 2009 and 2010 guidebooks, so I have 6 practice tests.</p>
<p>By the way, do you know where I could get a copy of the 2007 Official Student book, or the 2006 one? Could you like scan it in for me or something?</p>
<p>When you get your test results, they will stipulate what the average expected range is for someone who gets the numbers you actually get. I believe all of your results are within that range. Even if they are not, bear in mind that there are a significant number of students who do get outside of the average expected ranges when they take the tests a multiple number of times. </p>
<p>My son got perfects on most of his SAT Math tests. Could not do it on the real thing, however. Just the way it goes. Did better than his trial runs on the verbal, however.</p>
<p>The practice tests from CB have a curve. They give you the same curve that was used for people who they administered the test to. It’s an accurate representation of what you would get on the PSAT. Of course, it might be a bit off, but it’s not like you will get a 220 on a practice PSAT from the CB and a 200 on the real thing when you take it.</p>
