This is the only comprehensive review system that exists. While it may not teach you everything, it teaches you what you need to PASS and be comfortable.


The material tested by the core exam is immense and intimidating. The board review course and the Crack the Core Exam books provided a focused, high-yield method to approach studying for such a seemingly overwhelming exam. I listened to the entire board review course about 4-5 times and read through the review books twice. I also read through the dedicated physics review book, The War Machine, and the case companion books. I am confident that this helped me feel prepared for the core exam, dominate each section and pass the exam with a score well above the passing cut-offs.

Prometheus provided a refreshing synthesis of the board contents and conveyed them in a succinct, clear, and occasionally comical fashion.


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.


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