Which exams does this cover?
All three components of the CDA exam: General Chairside Assisting (GC), Radiation Health and Safety (RHS) and Infection Control (ICE). You can study for one, two or all three.
Are these real DANB questions?
No. Every question is original and written to the published exam outlines, with an explanation for every answer choice.
Do the practice tests match the real exams?
Each practice test has the same number of questions and the same time limit as the real component exam. The official exams are computer adaptive, while ours are fixed forms so you can compare attempts.
Does the radiography practice use film or digital?
Digital. The current radiation health and safety exam tests digital imaging, so our practice focuses on sensors and phosphor plates.
