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.

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.

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

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

All I wanted to do was pass my boards. I studied two question banks, Crack the Core, Board Buster videos and prayed for two months (prayers are ongoing). I didn't just pass, I did well and scored 560 (350 is passing). The Board Buster lectures were good and I would have watched them more but I had to turn them off around my wife and kids because of Lionheart's cursing.
