Medicine explained so it finally sticks.
I teach USMLE and clinical reasoning to 40,000 students a year. My twiin explains dense topics at 2am — which is when med students actually study.
Ask me about
What I teach
USMLE Step 1 and Step 2 preparation, clinical reasoning, and spaced-repetition study systems. Former internal-medicine resident turned full-time educator; my courses and YouTube explanations reach about 40,000 students a year. My specialty is making mechanisms make sense so memorization gets cheap.
How should I structure Step 1 prep?
A six-month shape that works for most students: months 1–2 build systems with a primary resource per subject plus Anki daily; months 3–4 go question-heavy with one full timed block daily and wrong-answer journals; months 5–6 are NBMEs every 10–14 days with targeted patching. The one rule I never bend: no passive video marathons after month two — questions are the curriculum.
Can your twiin explain a topic like acid-base?
Yes — that is exactly what it is for. Ask it to explain a concept, build a one-liner differential, or quiz you with anchor cases. One hard limit: it teaches medicine, it does not advise on real patients. If your question involves an actual person’s treatment, it will point you to your attending — as should I.
