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.

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”).

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.

I am proud to say I passed the Core exam. I don't know what I would have done without Promethius Lionheart. Words can't describe how great these resources are. I used Crack the Core, the Titan Radiology videos, the Case companion, and War Machine. Promethius's way of using Kinesthetic learning and humor is outstanding. He simply gets it. I already have been educating the new budding future-Titans on what resources to use. Needless to say, ALL of the Titan Radiology resources I consider mandatory.

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.
