studied maybe a total of 20 hours outside work the first 2.5 years of radiology residency. Not an exaggeration. Feeling the pressure, I decided to place my trust in Prometheus. Read all of his books, latest edition x2 and all the rad videos x3. Supplemented with a few questions banks and ipad physics app. Rest assured this is all you need. Forget Core Radiology by what's his name and burn your copy of Brant and Helms to keep you warm while you use Prometheus material. It is all you need. Ended up > 500 on the exam.

Will be buying his stuff again for the cert.

The videos are a great way to study and get through the book quickly. The video illustrations/diagrams also helped explain the physics concepts very well.

Learned a ton from your book, I wish I started using it earlier on. The way you present things just clicks!

I used CTC for both the ABR CORE and the written portion of the Canadian exam. Speaking specifically to the Canadian exam it was far better than Primer and other resources I had tried for targeting our MCQ section. It would not be sufficient for Oral exam prep, but its great as a starting point for organizing your knowledge base. He has a fantastic, engaging style of writing which kept me motivated for the long slog through 2 board exams this past year, both of which were successfully passed!

Prometheus and his study materials are the reason me and my 7 co-residents all passed the Core Exam. All of his resources are high yield and should be essential to any resident's study plan!
