After doing many NBMEs for both Step1 and 2, and I've to a very simple, yet hard to interiorize conclusion:

Most of the times when reading a vignette and thinking: "No way this is the answer, they want me to choose this but its just to obvious, there has to be a catch".

Thats actually the correct answer.

Every time this has happened to me, I choose a different one thinking there most be a trick and then when reviewing the test, it turnes out it was the answer that felt too easy at fist.

Just an advice to everyone cause I know we all overthink stuff sometimes, some more than others.

Hear me out.

Guyton and Hall is obviously not the most popular Step 1 resource. It is long, detailed, and sometimes goes much deeper into mechanisms, physics, curves, and regulatory systems.

Because of that, most students preparing for Step 1 or medical school exams tend to prefer more concise, USMLE focused resources: Costanzo, BRS, Boards & Beyond, First Aid, UWorld, etc.

My medical school relied heavily on Guyton for physiology, and right before graduating I started teaching physiology to medical students, which forced me to reread large parts of the book very carefully.

When I later started preparing for Step 1, I realized how much that foundation helped. A lot of Step 1 and Step 2 became much easier and intuitive because so much of medicine is built on physiology: cardiology, nephrology, pulmonary, endocrinology, vascular, neuro, and even many mechanisms behind pathology and pharmacology.

Guyton at its best, it is a narrative, almost a novel, of how the body works. It forces you to understand why normal physiology behaves the way it does, and once you understand normal function, disease often becomes easier to reason through instead of memorize.

I know most US MD/DO students probably will not have time to read it cover to cover, especially during Step prep. But if you are a premed, an IMG with more time before dedicated, or someone who wants a deeper physiology foundation, I genuinely think Guyton is worth considering as a core physiology resource.

It has been the greatest key to my success with the USMLE so even if its not for everyone, I wanted to share my experience.
