Notes made for one student, now shared with thousands
A graduate physician, walking the Match road himself
Dr. Adnan Memon, MD is a graduate physician and Match aspirant (2027 cycle). Like every USMLE candidate, he spent his own Step journey trying to turn dense clinical knowledge into something he could actually recall under exam pressure.
So he started sketching flowcharts — simple, branching yes/no diagrams that mapped out how to move from a chief complaint to a diagnosis, the same way a clinician reasons through a case at the bedside. They were never meant to be public. They were his own study notes.
When he began posting them on Instagram to keep himself accountable, other students preparing for the same exams started asking for more. That page has since grown into a community of 24,000+ followers, alongside a Facebook page of 20,000+, and a growing YouTube channel walking through the reasoning behind each flowchart.
Medicine is a chain of decisions — so we teach it like one
Most USMLE prep asks you to memorize facts in isolation. The algorithmic method instead teaches the path between them — because that's what the exam, and real patients, actually test.
Start from the complaint
Every flowchart begins where a real encounter begins — a symptom, not a diagnosis — because that's where every USMLE vignette starts too.
Branch on the finding that matters
Each yes/no question is chosen because it's the single detail that actually changes the differential — no noise, no irrelevant tangents.
Arrive at a defensible diagnosis
By the time you reach an endpoint, you can explain exactly why — which is what separates recognizing an answer from reasoning your way to it.
From personal notes to a growing community
Flowcharts as personal study notes
Dr. Adnan begins sketching algorithmic flowcharts to organize his own clinical reasoning while preparing for his USMLE Steps.
Posting to Instagram
What started as a personal habit turns into shared content — the page grows to 24,000+ followers preparing for the same exams.
Expanding to Facebook
A companion Facebook page reaches 20,000+ followers, extending the same flowchart method to a wider audience.
Launching on YouTube
A new YouTube channel walks through the reasoning behind each flowchart in video form, for students who want the method explained step by step.
