Details
Who is Step 0 made for?
Step 0 was designed for Medical Students studying for the CBSE or Step 1 exam. It is especially recommended for those who are just beginning to study for the exam; prior to starting UWorld question banks.
What is the benefit of Step 0?
Step 0 breaks down complicated Step 1 level questions into a storyline; allowing students to understand the process and mechanisms behind each clinical correlation rather than memorizing.
Is Step 0 a replacement for UWorld?
Not at all! Step 0 is recommended as a study tool BEFORE moving onto UWorld and Bootcamp questions. We are not trying to replace any other resources, but rather aid students in the study process to produce more efficient study time.
How does Step 0 coordinate with resources like UWorld, Anki, and First Aid?
Step 0 does not replace comprehensive question banks: it builds the foundational clinical reasoning needed to actually retain them. We recommend anki decks for memorizing, Step 0 for understanding, and UWorld to put it all together.
The foundational blueprint protocol empowering pre-clinical and medical students to master foundational concepts before Step 1 prep.
