It’s difficult to have a perfect study source for a wide subject like Radiology, but this is certainly pound for pound the BEST resource available!

Just took the test this year and passed. The Crack the Core books are a must use! The way he explains it makes things, even extremely dry concepts, entertaining and simple. I cannot recommend this material strongly enough.

Crack the Core is essential to passing the Core exam. Every resident at my institution used it as their primary resource for both the imaging diagnosis and physics portions of the exam. I felt as prepared as I could have been thanks to Prometheus and his resources. These books will be useful far past the core exam, and I’ve seen many fellows that come from outside programs frequently referencing it. Thanks Prometheus, I couldn’t have done it without you.

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

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.
