CMS exam prep — PYQs, exam modes, and clinical tools in one app.
CMS Prep is a question-bank app built around the actual Combined Medical Services exam. It ships all 17 CMS papers from 2016 to 2024 — roughly 2,040 questions — organized by year and subject so you can drill exactly the block you’re weakest on.
Every question comes with a full explanation: a concept overview, option-by-option analysis, and clinical pearls. Alongside the question bank, the app includes over 100 offline clinical calculators spanning 12 specialty areas — emergency, cardiology, renal, neuro, ICU, and more.
The handful of things it does, done properly — nothing bolted on for a feature list.

Full explanation cards
Every question ships with a concept overview, option-by-option analysis, and clinical pearls — not a bare answer key. The kind of explanation you would write for yourself.
