Hey Prometheus, First of all, I just want to say you're a boss. Thanks for making radiology cool and understandable for not just me, but for all the radiology residents across the US. If it wasn't for you, I honestly don't know what I would do. I'd probably be in a heap of trouble.

Boards Buster is the perfect compliment to crack the core. Prometheus narrates some of the more complex sections of the books and also drops some additional knowledge. Not everyone in my program used the videos - but I used this to my advantage as I felt better prepared to dominate the exam.

THANK YOU for your enthusiasm and effort! By far the easiest videos to sit through – your sense of humor was MUCH appreciated, and helped immensely when trying to suffer through otherwise mundane material (i.e. “Non-interpretive skills”).

Prometheus provided a refreshing synthesis of the board contents and conveyed them in a succinct, clear, and occasionally comical fashion.

The online review course was a great compliment to the book series. I found this online review course much more helpful than the week long review course I attended. Crack the Core series is the boards review standard. Thank you for the effort you put into both these resources. You did and wonderful job.

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.

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.

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!
