Has College board been known to reusing some of the questions from their released exams, such as from 2009?</p>
No. If the questions are available to the general public, they won’t be used on any regularly administered AP exam. I say “regularly administered” because I remember reading somewhere on CC that someone taking the makeup-makeup AP Calculus exam apparently got the 2008 exam, which was released, but unless you’re taking a multiple-layers-of-alternate exam, you won’t see any questions that have been released.</p>
