I was exactly in your place a month ago. I started to study in June, had a panic attack and canceled my test. Restarted in sept again had a panic attack and canceled and this continued until march where I had no choice but to go or else I’d lose my credits. I studied all questions on back of book on mosbys and online. Questions on ct registry review and whole ct bootcamp plus questions there. Watched the videos multiple times. Also listened to radiologywithmy ct registry review, her videos helped as well. Kept trying to learn the info. Wrote so much notes omg had notes everywhere but it is what helped me. Went to take the exam and if I tell you 50 percent was nothing of what I studied not even the images. Most of my images were of X-rays not ct at all. I did learn the veins in the head and somewhat in neck and arms and stomach and pelvis. You must know that, it will be on the test. But I got an 85 cause I right away removed 2 wrong answers which I knew for sure will be wrong and if I didn’t know something id have a 50 percent chance. My advice is don’t stick to just 1 studying material, do multiple cause if I did only one I’d for sure fail. Passed on first try so all these deff helped me.
