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!!

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.

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.

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.

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.
