I have had the worst experience with college board. I have never in my life dealt with a company that is so rude to its customers. College board made a huge mistake and I have been treated like I am the one that made the mistake. A testing center took all the kids' calculators erroneously and now college board is pretty much saying, "oh well.. Sorry about you! I filed a formal claim the day that my child took the test. The issue was purposely drawn out so now they say everything is locked and they can't help me. They never wanted to help me in the first place. They say that something could have been done within the first nine days. I called the day that he took the test!!!
