Paramedic NREMT Prep · Est. 2026
Pass the NREMT the first time.
The real exam is computer-adaptive — flat practice tests can't prepare you for it. Korsa is built on the same 1-PL Rasch model the National Registry's CAT runs on, with 2,400+ calibrated questions that find your weaknesses before test day does.

№ 01Why Korsa exists
1 in 3 don't pass their first attempt.
Every retake costs $175 out of pocket and at least 15 more days on the clock — usually after months of grinding static practice tests that look nothing like the computer-adaptive exam you'll actually sit.

№ 02The engine
Practice that thinks like the test.
The National Registry doesn't grade on raw score — it estimates your true ability with item response theory. Korsa is built on the same 1-PL Rasch model, so every session is a rehearsal for the real thing.
- ✓Every answer moves the needle
Get it right and the next item is harder. Miss it and the engine calibrates down. No two sessions are the same.
- ✓True ability, not a percentage
Korsa estimates the same ability score the real CAT computes — so your results actually predict performance.
- ✓A pass-likelihood you can trust
After every exam: your probability of passing, plus a domain-by-domain weakness map that tells you exactly what to study next.
№ 03The question bank
2,400+ questions. Zero filler.
Every item is calibrated and mapped to one of the six NREMT cognitive domains — written against current paramedic curriculum and the 2024+ exam formats, including the new technology-enhanced items.

№ 07FAQ
Straight answers.
Is Korsa really adaptive, like the actual NREMT?
Yes. Korsa runs a 1-PL Rasch item-response-theory engine — the same model family the National Registry's computer-adaptive test is built on. Answer correctly and the next item gets harder; miss and it calibrates down. Behind the scenes, every session estimates your true ability, not just a raw percentage.
How big is the question bank?
2,400+ active, calibrated questions across all six NREMT cognitive domains — Airway, Cardiology, Trauma, Medical/OB-GYN, Operations, and Clinical Judgment. That includes realistic ECG strips and monitor readouts, roughly 15% pediatric cases, and the 2024+ technology-enhanced formats: multi-response, drag-and-drop, build-a-list, and option-grid items.
Do I need a credit card to start?
No. Creating an account starts your 14-day free trial immediately — you only enter payment details if you decide to subscribe.
What's included in the free trial?
Two full-length adaptive exams (up to 150 questions each, variable-length just like the real CAT) per rolling 72 hours, complete result breakdowns, and flashcards — enough to feel exactly how the engine works before you pay a cent. Quick 20, weak-area drills, and study notes unlock with Pro.
What happens when my trial ends?
Korsa locks until you subscribe — but nothing is deleted. Your exam history, weakness profile, notes, and flashcards are all waiting when you upgrade.
Can I cancel anytime?
Yes — one tap in Settings, right inside the app. No phone calls, no emails, no retention games. You keep Pro access through the end of your billing period, and you can resume just as easily.
Can I use Korsa on my phone?
Korsa runs in any modern browser, and you can add it to your home screen — it opens full-screen and feels like a native app. Your account syncs across every device you sign in on.
I have a question or a billing issue. Who do I talk to?
Email korsasupport@gmail.com or use the support form inside the app — a real human reads every message.
