Kaplan Radiography Exam with CD-ROM 1st Edition Edition

I have bought several Radiography review books to help me through classes and prepare for the Registry test. This book has been the least helpful of the ones I bought. It appears to cover every subject one needs, only the questions seem really easy. There are also several questions I have found with incorrect answers. One that I remember particularly is on page 42. Question number 6 refers to a diagram of a lateral skull. The question reads "The organs of hearing are located within which numbered structure?" The frontal bone is labeled (1), Parietal bone is (2), Occipital (3), Temporal (4), Sphenoid (5). The answer in the back says it is (1) the frontal bone, which is clearly incorrect. There are a couple of others, but I can't remember them at this time. Also, the disc that comes with the book doesn't have a lot of information on it. I've already removed it from my computer. I recommend Mosby's or Appleton & Lang. Both are good review books with complete practice tests on disc.
