<p>well unlucky dont read the post and reply to it if it annoys you. i believe that airforce is failry accurate in his calculations so dont hate. haters only die horrid deaths</p>
<p>chrichessill-assuming you missed none besides the ones you mentioned and taking a total of 3 off for forgetting to multipy by pi (I have no idea if that's what they would take off for that) you would have ~78 which is well within the range of a five.</p>
<p>I heard the lowest raw score for a 5 thus far has been 54 or so out of 108 (don't know what year)</p>
<p>I'm hoping this year's will be in the low 60s....
I found some free response parts to be easy...many to be pretty hard....so who knows...
multichoice wasn't all that bad...part B was surprisingly (maybe deceptively?) easy...</p>
<p>1) Equating, using a comparison of questions from last years MC as compared to this years MC (this is why you never talk about multiple choice questions, because they stay the same from year to year...at least some of them)
2) The Chief Reader then finalizes the composite scores required for a 5,4,3,2,1.</p>
