<p>Guys do you think the curve will be lenient? I left 5 blank and probably made at least 7 mistakes, I’m freaking out :(</p>
<p>Patience is a virtue! Tough to predict how they’ll curve this exam (or as they say"recenter the score scale"). But 5 wrong and lets just say 10 wrong for rounding purposes and that gives you a raw score of 73. </p>
<p>That’s anywhere from 750 according to PR’s old exams to 770 E and 780 M from CB’s blue book 2010-11 SAT Bio E/M practice exam. </p>
<p>That’s approx 90th percentile for E and 85th percentile for M when compared to 2013 college bound seniors. That’s a strong score and well above the 2013 averages of 626 (E) and 655 (M). </p>
<p>@DaneBrick 5 blank and 7 wrong is -14 off your score, raw score of 66, which is probably like around 700</p>
<p>@fleemur 10 wrong gives a raw score of 68, and not 73 … which is a 740 on Bio E and 750 on Bio M according to the CB’s blue book 2005-06 </p>
<p>generally speaking with 5 blank, what’s the most I can get wrong and still manage to get a 700?</p>
<p>@sahil9797 @alfawarlord - right. </p>
<p>Simple version:</p>
<p>(# of right answers) - (0.25 x # of wrong answers) = raw score</p>
<p>@fleemur I hate to burst your bubble if I get +1 for each correct answer, wouldn’t that only be 68, not 75?</p>
<p>Yup. I was missing something there. </p>
<p>61 raw for Bio E and 60 raw for Bio M. With 5 blank, you can get 11 questions wrong for the E and 12 wrong for the M. That’ll give you a 700 according to the CB blue book conversion chart. If my math is right…</p>
<p>Guys I’m pretty sure I got only 2 wrong but just in case. Would 3 wrong be an 800?</p>
<p>@fleemur how old is your CB blue book conversion chart. also do you think this test was hard enough for such a curve?</p>
<p>@DaneBrick it’s from the second edition of the CB blue book with a 2011 copyright date, but I have a feeling it’s the same one from the first edition from 2006 b/c @sahil9797 was getting the same raw score conversions. That suggests the scales are identical i.e. old. The only comparisons legally available are probably just as dated since they’re from publishing companies. However, let’s compare your potential raw score of 68 and convert them using the conversion charts available to us.</p>
<p>Barron’s: 68 = 760 for both Bio E and M.
PR: 68 = 720 for both Bio E and M.
McGraw-Hill: 68 = 760 for both Bio E and M.
CB: 68 = 740 Bio E and 750 Bio M. </p>
<p>So there’s a range of 40 points in your scaled score depending on the curve, with PR having the least “equated” (curved) scale, PR and McGraw-Hill having the most equated scale and CB being in the middle of the pack. </p>
<p>Was this test hard compared to other SAT Bio tests? I personally didn’t think so, but that will be determined statistically by CB and the scaled score adjusted accordingly. I’ve never seen any “modern” conversion charts and don’t know of anyone outside of CB who is privy to them. The only modern data CB has released is percentile ranks for the subject tests for 2013 college bound seniors. That allows comparison of students to each other but reveals little about the curve applied to the scaled score. My wild guess is that the curve will be intermediate/low and a 68 may convert to about a 730. </p>
<p>@freeapftw since we don’t know what the conversion tables for this exam will look like, we can only estimate by using the existing tables available to the public. </p>
<p>Using the chart in the CB blue book, the lowest raw score that converts to an 800 is 77 for both Bio E and Bio M. So if you didn’t leave any questions blank, you can only get two questions wrong to get a 77/800. Answering three questions wrong will give you a raw score of 76 which converts to a 790. </p>
<p>I think the test was hard enough for a raw 75 or 76 to be a 800 as well… </p>
<p>@sahil9797 I hope you’re right because everyone at my school said this was really easy. I’ll admit the questions were pretty simple but I regret making such silly mistakes. looks like I’m taking this a 3rd time in the fall :(</p>
<p>Suppose i got 14 wrong (answered) and 4 wrong (unanswered)… Will i be able to pull atleast a 700?</p>
<p>@hrock500 if we’re using fleemur’s scale then you would have a raw score of about 59, so at that point it really depends on the curve. I’m praying for you because I might be in a similar boat</p>
<p>wait, i got like two wrong so far i think
i didn’t omit any questions
what’s probably the max you can get wrong for 800 this test?</p>
<p>@hrock500 your raw score would be 62 - (0.25x14) = 58.5 or 59 (just like @DaneBrick said). That converts into a scaled score of 690 for both Bio E or Bio M, using the CB blue book’s conversion table. So you’re close to a 700 and depending on the curve applied to the 6/14 test, you may get a 700. </p>
<p>@BasedBioGod if the test you just took has the same exact conversion graph as the 2011 CB blue book, without omissions, the max number of questions you can miss is 2. </p>
