Worked well for me! Used all the books and the review course~~ it was great! many thanks

I passed both the Core and certifying exams largely because of you. You should be proud. You taught me more than anyone else in radiology.

I would like to thank you for writing and continually updating crack the core and war machine. I would be a worse radiologist and would not have passed the core without these books. Your sense of humor and straight to the point explanations are greatly appreciated. For the sake of future residency classes, please continue fighting the good fight.

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.

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.
