<p>How does the curve work for bio could you explain</p>
<p>yes please someone explain this curve already. i’ve heard its predetermined, but my teacher told me apparently they only grade like 55 of them, and drop some of them, and THEN on top of that, they curve it.</p>
<p>well last year was around an 80% for a five, which is really high for an ap test. In my opinion it is predetermined because otherwise the percentage of fives would not have dropped by over 15% from last year. I think they just cut off the raw scores and made each for a five, four, three, etc.</p>
<p>Whatt? so its very leniently graded </p>
<p>how does the CB choose which questions to drop?</p>
<p>I dont think so, at least not for the new AP bio. Basically more people pass, less people get fives and ones.</p>
<p>So its basically designed to get 4s and 3s and so everyone passes ? Is it curved up?</p>
<p>No, its not curved up… its more of a bell shaped distribution with very few getting fives and ones and most people getting threes, fours, or twos.</p>
<p>its stabilizing selection to shift score distribution to the intermediate and away from the extreme</p>
<p>So more people are able to pass the exam right?</p>
<p>but the practice tests that we took were graded with a 77.5% as a 5
but I don’t see how theyre going to grade this year’s, considering that form O seems like it was significantly harder than any of the other forms, unless they do different scales for different tests
(does anyone else think form O was really hard)</p>

<p>Hiya guys. I know that there was a document floating around, but there were a lot of ■■■■■■ on it. So, I made my own document where I answered a lot of major questions that people seemed to have.</p>
<p><a href=“Answers to Major Questions in the 2014 Bio Exam - Google Docs”>https://docs.google.com/document/d/1oNrVvy_c7FPg3muqvIzm8QbZesuW_q1bArkZVXkeqHA/</a></p>
<p>It’s read-only. I’ll try to see what other major questions people seemed to have about it, and post solutions on it.</p>
<p>is anyone taking AP Chem next year</p>
<p>@weizhong Thank you! I had the same answers as you (except for pedigree) and was becoming less sure of myself as other were posting other things. I honestly had never heard of traits being passed via mitochondria, so I totally missed that one…</p>
<p>However, it really does seem like O had a much harder form than the others…does anyone know if this happened last year and how CB curved them? </p>
<p>Edit: @sIronMan CB is College Board. </p>
<p>what is CB</p>
<p>for the GMO crops…I got the lack of genetic diversity…but even though the point is to be resistant to those insects, wouldn’t the GM plants contribute to the decrease of insect population which could harm the ecosystem? I feel like that should be an answer</p>
<p>@schakrab isn’t that an answer? That’s what I put</p>
<p>Many of these questions feature a wide range of answers that depend on how well you argue your point.</p>
<p>The questions were too general would someone tell me what CB is?</p>
