The PSAT and SAT datasets gathered for this study are statistically different,
improvements can be expected IN GENERAL between the PSAT and SAT,
the law of diminishing returns applies; that is, improvements lessen with higher starting PSAT score, and reverse (causing deprovements) in the two top PSAT decades.
A large amount of data scatter makes precise prediction of any individual SAT score impossible,
However, prediction within roughly a 100 SAT point accuracy is possible for the majority of SAT test takers; nevertheless, large, unpredictable variations will still occur for numerous test takers.</p>
<p>PLEASE REMEMBER THE CAVEATS AND LIMITATIONS OF THIS ANALYSIS DESCRIBED EARLIER.</p>
<p>Advice I will give to my kids:
Dont lose hope, improvements are definitely possible, and in fact likely for most test takers,
Conversely, doing worse on the SAT is still very possible,although average losses are substantially smaller than gains,
This study did not approach the causality of improvements, hence stick to conventional wisdom of good preparation & rest, and certainly do not get over confident.</p>
<p>ALL FOR NOW…stay tuned to that exciting new SAT vs new SAT thread!..PC</p>
<p>We had very few data in the PSAT range below 160, hence I made the call to cut the data off below this limit. I thought it would be too much of a stretch to include those handful of wide-spread data, and subsequently concentrated on the 160 to 240 PSAT range. Judgement call on my part. Inclusion of your momumental improvement (I’d say you were the poster child here!) certainly fits into the conclusion that larger improvements are observed for lower starting PSAT values.</p>
<p>My PSAT with no preparation or any previous knowledge that there even was a “writing section” was a 192. After some prep I scored 2280 on the real new SAT, for a total increase of 360 pts.</p>
<p>I know a guy who went down from a 237 to a 2070, mainly because he hadn’t looked at any SAT type test for half a year before the real SAT.</p>
<p>kana-- your score couple is within the 95% confidence bracket as you can see by looking at post 241 above, with your improvement of 200 points being close to the mean for the 180 PSAT decade.</p>
<p>flipsta…on the other hand, both score couples that you report are outside the 95% confidence range, signifying that extreme good or bad can still happen to any individual no matter what the statistics on the group imply.</p>
<p>With your initial PSAT score, you’ve got plenty of upward SAT 1 potential. Suggest you put some prep time in prior to your next sitting, per Xiggi advice.</p>
<p>I certainly thought CR on PSAT last year was very hard especially with the reading passages talking about stuff like parapsychology, but I think people just recognize that they should improve upon their PSAT score and most study for the SAT.</p>
<p>Also, most people don’t study for the PSAT, including me (stupid idea–could have been an NMF). Then, when they realize how crappily they did on the PSAT, they prepare at least a little.</p>
