<p>My daughter took the AP psychology test on Monday. Something happened at the testing site (took place at the local community college) where someone cheated, and the psychology teacher told her class that all of the tests may be invalidated. Has this happened to anyone before? My daughter thinks she at least got a 4, but probably a 5. Now she may not get any credit at all. The teacher told them that if it's invalidated, they would have to take it next year (and pay for it themselves ... where right now the school board pays for the exam fees). I'm livid because she has worked hard all year in order to do well on this test.</p>
