I struggled initially with Radiation Biology concepts, especially the long-term effects of radiation. The Prephow practice test simulated the actual exam environment perfectly. It ensured I was solid on all aspects of Patient Exposure to Radiation and the ALARA principle. Passing the first time was all thanks to this prep!

I needed to brush up on Purpose and Maintenance of Radiographic Equipment and the practical application of the Inverse Square Law. The questions were challenging but fair, mirroring the real RHS difficulty. After focusing on the areas Prephow highlighted, I felt completely prepared for the official test. Worth every penny!
