SynkMind™CCRN
CCRN · one course, the whole exam

The numbers on the monitor are the exam. Learn what each one is asking for.

MAP, CVP, cardiac index, the gas, the lactate — the CCRN hands you a critically ill patient and asks what the nurse sees, anticipates and does first. Every lecture here teaches the ICU from the physiology up, and every practice form is weighted to the AACN test plan, Synergy Model included.

Five body-system areas, plus the Synergy Model

Every question tagged to its test-plan area. Your score on each one.

The CCRN is 150 questions, pass or fail on the number you get right. Here every item carries its test-plan area, so your analytics show which part of the ICU is holding you back — and the two Gauntlet forms are harder than the real paper on purpose.

Mock exams

Six full-length mocks, built to the real paper’s outline.

The real paper is 150 questions in three hours, 125 of them scored: 80% clinical judgment across the body systems, 20% professional caring and ethical practice (the Synergy Model). Our full-length forms are the same shape. Every item is original and board-style, weighted across AACN test-plan areas the way the exam is — so a score here means something about the score there. 2,090 questions in all, counted once.

  • Timed, full length, with the clock the exam uses — or tutor mode, explaining as you go
  • Your own filters by topic and difficulty, and a form of only what you got wrong
  • Every explanation carries the key facts and the pitfalls, not just the answer

Axon Live

A tutor you talk to. Out loud, on a board, on the body.

Say what you are stuck on. Axon teaches the section in the voice of the adult critical-care nursing certification (AACN CCRN), draws the reasoning on a whiteboard as it speaks, and when the point has a place in the body it rings the structure on the 3D model and asks you to tap it. It knows your syllabus, your weak spots and where you left off.

  • Five modes: Teach me, Quiz me, I’ll listen, Why I missed it and Cram
  • Fifteen free minutes to meet it; top up in packs from 15 minutes after that
  • Every session leaves a recap you can reopen

The Body

A male and a female body you can turn, peel and quiz.

Every system a switch, every structure a name, a definition and a door to Axon. The heart beats, the lungs breathe. Peel from skin to muscle to organs to bone, paint your own scores onto it to see where you are weak, and let Find-it quiz you by tap. Open it from a lecture and it shows what that section names; open it from any explanation and it takes you to the structure the question was about.

  • Two reference bodies, openly licensed and credited
  • Labels, x-ray, isolate, your heat map, keyboard — built for a study hall, not a showroom
  • On your phone too: it folds to a sheet

The plan that reschedules itself

A plan built from your week, not your good intentions.

Tell it your exam date and your week — or hand it a screenshot of your timetable. It schedules sections by the minutes they take, gives every lecture seven spaced looks, moves what you missed, tells you what changed and why, and the Today screen names the one thing to do first.

  • Weak Spots: your true topic scores, settled from every attempt
  • Smart Practice: spaced repetition on the questions you missed
  • Learn · Test · Rehearse — three verbs, and a reason on every row

Analytics

Know your number before the exam does.

Every sitting lands on a trajectory against the passing standard. Areas are ranked, an exam coach reads the chart with you, and the same numbers drive the plan — so what you see is what the product acts on.

  • Score trajectory, by sitting and by day
  • Content-area breakdowns with the standard drawn on
  • An AI coach that explains the chart in plain words

Why it is honest

Nothing here was copied. We say so because it matters.

Question banks in this field have a habit of leaking. Ours cannot: every item is authored to the public content outline, checked by a second AI model that never sees the key, and fixed or dropped if the two disagree. The number on this page is the count after every duplicate is removed — never the sum of the pools.
