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”).

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.

Normally i dont care enough to review anything. In fact this is the first review i have ever written in my entire life. I leave that for the betas. But I just gotta say your videos are perfect. The high yield points presented in such a concise manner. Also I 100% agree with all you side points which makes me laugh out loud and keeps me going. So i guess thanks, for whatever its worth.

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

I passed the CORE because of you!! Thank you so much for all the hard work compiling these resources. You are the MAN!! The Goljan of the CORE!!

Thanks for helping this dumb jock pass the Core. Your materials are definitely the best out there.

You are a freakin boss. Your books are incredible, the only thing better than your books are The Requisites (just kidding those are awful!). Please start your own residency program.
