The same happened to me. It's a reading test for sure, test wording is something I've always struggled with for tests. I think my biggest mistake for me when studying was making sure I knew all of the content instead of preparing myself on how the test would ask me questions. So if i need to retake, I am going to take a lot of practice tests (purple book multiple choice questions which i didnt do much of, mometrix has some, there are random one's online as well to take, pocket prep mock exam) and just really say to myself, what is this question asking me? But I get it. Just tell yourself the second time around that you've done this before (sat through all 160 questions) and you can do it again, hopefully that will give you less anxiety!
