<p>Anyone who is willing to shell out the money, and show up on exam day, can take the AP exams. A number of adults who write about education issues have done just this.</p>
<p>Whether or not the college/university in question will give you credit/placement for that exam is an entirely different story. You should verify that you will be given credit/placement for a given score before you spend your money on a “late” AP exam.</p>
