AP Bio curves

<p>what is the general range to get a 5,4,...and how to calculate your score like what do you multiply by?</p>

<p>take the multiple choice score, subtract 1/4 the number of wrong answers. and then multiply it by around .75. Then take each essay score and multiply it by 1.5. add the two together to get your composite out of a total possible of 150
109-150 is usually a 5
70-108 is a 4.. etc.
correct me if i'm wrong anybody</p>

<p>I think that curve is off by a lot.</p>

<p>My Princeton Review AP Bio book for 2006-2007 says the following:
Greatest possible raw score = 135
83+ = 5
63 - 82 = 4
something like that</p>

<p>I think the curve on the last post is too harsh.</p>

<p>yeah, sorry man, just checked it myself (that is right for a couple of the other tests i took this year), i knew that curve was too high... this is what it was for the 2002 AP bio exam... 91-150 is a 5, 70-90 is a 4, 58-69 is a 3.. obviously the 91/150 for a 5 means that the curve is pretty low (about 61% right =5).
So don't stress if you don't know everything there is to know about biology, the collegeboard, the sages that they are... don't think you need to.
good luck everybody!</p>

<p>Hmm, on Collegeboard, MC has a weight of 60% while FR has a weight of 40%.</p>

<p>yeah, just saw that too, but if you ace the multiple choice a full 120 right, the weighted number is 90, and for FR is 60.<br>
60/150 = 40% 90/150 = 60%</p>

<p>the new ap test is only 100 multiple choice. how does this affect the scoring? what calculations do we have to make to derive our score?</p>

<p>hmmmmmmm, i did not know that at all... perhaps the multiplier for multiple choice is higher, instead of .75 like it was when there were 120 MC. if that is the case, the multiplier is now .9 so that 100x.9 = 90, which with the 4 essays still being worth 10 points and a multiplier of 1.5 gives 60. and 90+60 = 150.. unless RCman's princeton review book is right with the total composite being out of 135, which is odd, cause all AP tests i've ever taken have been out of 150</p>

<p>Here is the complete way to calculate your score. Multiple choice score x .7563. Remeber every wrong answer is an additional .25 pts off. Then take each essay score and multiply by 1.500. Then combine all numbers. </p>

<p>Generally</p>

<p>91-150 is a 5
70-90 is a 4
58-69 is a 3
45-57 is a 2
0-44 is a 1</p>

<p>Also let's say you only want to take the MC part. Use this scale:</p>

<p>Use For Weighted Score
5 is a 76-90
4 is a 61-75
3 or 4 is 46-60</p>

<p>that multiplier is only right if there are 120 questions(in that case 119 cause in 2002 where that number comes from one of the questions wasn't counted), if there aren't the multiplier must be higher in order to give the 60% weight to MC.</p>

<p>there are only 100 MC questions this year. this change was implemented beginning last year, i believe.
i dont know how that affects the scoring/curve.</p>
