Prometheus and his study materials are the reason me and my 7 co-residents all passed the Core Exam. All of his resources are high yield and should be essential to any resident's study plan!

Although these videos are aimed at the US boards, I found them incredibly helpful for the UK FRCR exam. The style of teaching is engaging and the information is accurate and concise. The great thing about videos as apposed to other learning resources is that you can learn a great deal when passiveley listening but of course you have to consolidate that knowledge with further reading and practice. Thank you for making revision more enjoyable!

I used CTC for both the ABR CORE and the written portion of the Canadian exam. Speaking specifically to the Canadian exam it was far better than Primer and other resources I had tried for targeting our MCQ section. It would not be sufficient for Oral exam prep, but its great as a starting point for organizing your knowledge base. He has a fantastic, engaging style of writing which kept me motivated for the long slog through 2 board exams this past year, both of which were successfully passed!

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.

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.
