Were there two forms for the 2012 AP Physics C exam?

<p>So it's finals week and I'm procrastinating by reminiscing about the AP exams I took in high school. I took Physics C Mechanics and E&M in the spring of 2012, and something weird happened. Half of our class (including me) got the normal form of the Mechanics exam, for which the free response questions are now listed on the Collegeboard's website. But the other half of our class got a completely different set of free response questions. There is no record of these questions on collegeboard's website, nor have I ever seen mention of them anywhere on the College Confidential threads discussing the AP exam. As far as I know, these exams were still scored as if nothing out of the ordinary had happened.
Did anyone else get a different form of the AP Physics C Mechanics exam in 2012? I believe it included a roller coaster question.</p>

<p>That happened today (2013). Two different forms, two different sets of questions.</p>

<p>I wonder if they’re gonna be curved separately…</p>

<p>They definitely have to be curved separately, because the other form (the one I didn’t take, unfortunately) was wayyyy easier. It would be pretty unfair if they were curved the same.</p>
