<p>and the curve for a 5 is 129/180.
However, on the 2009 released exam, for example, the curve is 111/180 for a 5.</p>
<p>What gives? Did they really change the curve that much, or do they just curve "international exams" harder?
And to anybody who took the Physics B exam this year, what do you think the curve would be around for a 5?</p>
