USMLE-Rx
USMLE-Rx is a study system for medical school coursework and USMLE board preparation, available on the web, iOS, and Android. Its Rx360+ collection combines Qmax questions, Rx Bricks learning modules, Flash Facts with Study Stream spaced repetition, and Express Videos. Qmax covers USMLE Step 1 and Step 2 CK and includes self-assessments, progress reports, and predictive scoring. Rx Bricks provide interactive medical learning modules with explanations, objectives, flashcards, and practice questions. Flash Facts schedules review cards at calculated intervals and revisits weaker areas more often. The tools connect questions, concepts, videos, and flashcards. Users can share Flash Facts decks and Qmax tests with classmates, and share Express Video playlists. A five-day Rx360+ trial is available, and access to over 150 Bricks remains free afterward. Separate Qmax, Rx Bricks, Express Videos, and Flash Facts plans are also listed, but no prices are provided. Plans are billed once for the selected duration and do not renew or charge automatically. SmartNotes remain accessible after a subscription expires.
