Why this site exists

Siddharth Sah — MBBS student, Fujian Medical University

I'm preparing for USMLE Step 1 and building my way through the core basic science subjects. StepWise USMLE started as a set of study notes I was building for myself — condensing lecture material, textbook chapters, and question-bank patterns into something I could actually revise from before exams.

Over time those notes turned into something worth sharing. This site is the public version of that library, and the same name and school are listed on the StepWise USMLE YouTube channel for anyone verifying this is the same person and project.

Every page here is self-contained, built to be readable on its own, searchable within the page, and easy to print or save as a PDF. There's no login, no paywall, no tracking beyond what's needed to keep the site running.

These notes are built from lecture material, standard textbooks, and question-bank patterns — condensed and organized by a student, for students. I try to be careful, but this is study material made while I'm still learning the subject myself, not a peer-reviewed or clinically-vetted reference.

If something looks off, please flag it — I'd rather fix an error than have it sit uncorrected. Treat this as a companion to your primary sources, not a replacement for them.

Found an error, have a suggestion, or want a subject covered? Reach out through the channel's community tab or comments — I read everything.
