In order to cater for all students, the questions are arranged according to three levels of difficulty. They will meet the needs of those hoping to pass the Medical Dosimetrist Certification Board (MDCB) exam, candidates taking Medical Physics written exams (parts I and II), Radiation Oncology residents, and American Board of Radiology candidates or those taking equivalent exams elsewhere in the world.

The study guide is broken down into different subject areas, with provision of multiple questions and answers on each subject. In addition, the mathematical and physics questions include brief explanations of how the student can solve each problem. At the end of the guide, three practice tests are included with the same number of questions as are found in the MDCB exam.  These tests will help students to test their knowledge and improve their test-taking speed.
