Your ABRET CNIM prep, in 48 seconds
Diana walks you through the dashboard: practice by topic, timed mocks, weak-spot tracking, flashcards, study notes and the Pass Guarantee.
Learn the reasoning behind every answer
The CNIM rewards technologists who can read a signal change and pick the right response. Every explanation walks through the neurophysiology, anesthesia effect or protocol behind the answer, so you learn why, not just what.
- Original questions written to ABRET's CNIM content outline
- Trap answers called out, like an anesthetic change vs. a true surgical change
- Practice by topic or mixed, with instant feedback
See your weak spots before the exam does
Your Readiness Score day by day, accuracy by topic with the weakest first, and every timed mock exam against the pass line. One click on a topic starts a drill on it.
- Topic accuracy updates after every question
- Mock exam scores plotted against your target line
- The Today list sends you to your weakest topic first
Remember it on exam day, not just tonight
Spaced repetition brings each card back right before you'd forget it. Cards you miss return in 10 minutes. Cards you know wait days or weeks.
- Generators, anesthetic effects, muscles and alarm criteria that get tested
- 15 new cards a day, so reviews never pile up
- Mastery feeds straight into your Readiness Score
Turn every missed question into a point
Every question you get wrong is saved with its explanation. It only clears after you get it right twice in a row, so lucky guesses don't count.
- Re-test all your mistakes in one click
- See the right answer and the concept behind it
- Shows how many you've cleared, to keep you going
Walk in having done it before
Timed mocks with no feedback until you submit, the way exam day works. The CNIM gives you 4 hours, so stamina and a steady pace matter.
- Full 4-hour mocks across all five outline domains
- Quick 25-question mocks between cases
- Two full simulations count toward the Pass Guarantee

Questions before you buy
Can I try it before I pay?
Yes. Open the study dashboard free with no signup, or take any exam's free practice test. You only pay when you want the full question bank, timed simulations and every study tool.
What if I buy it and it's not for me?
Because you get the full question bank and study materials the moment you pay, all sales are final. Try the free test and the free dashboard first so you know it suits you. The one exception is the Pass Guarantee: complete the full prep, and if you still fail, we refund 100%.
What if I study and still fail?
That's what the Pass Guarantee is for. Answer every question in the bank, read every study topic, pass 2 timed simulations and reach a Readiness Score of 80, then sit your exam within 60 days. If you don't pass, send your result notice within 30 days and we refund 100%.

Most people study for 1 to 3 months. If you want a whole year for one exam, the yearly plan is $1,323 for 12 months (3 months free) and renews once a year until you cancel.
How long do I keep access?
For as long as your Premium subscription is active. Cancel any time from your account and you keep access until the end of the month you've paid for.
Are these real exam questions?
No one can legally sell the actual exam questions. Ours are original questions written to match ABRET's CNIM content outline, format and difficulty, with an explanation for every answer and the guideline, generator or anesthetic effect behind it, so you can check our work.
Is the content up to date?
We check the exam page against ABRET's current CNIM Handbook for Candidates and website and show the date it was last checked. In November 2026 that included the 2026 content outline (Provider Communication and Documentation 27%, Preparation and Application of Fundamental Concepts 25%, Intraoperative Phase 25%, Post-Operative Phase 13%, Safety and Ethics 10%), the four eligibility pathways and the US$700 fee.
Do I still need the recommended IONM texts?
Yes. ABRET's handbook lists recommended texts (such as Husain, Simon, Møller and Nuwer) and the ACNS and ASNM guidelines, and they're your core reading. We're the extra practice: more questions, timed mock exams, flashcards and a Readiness Score so you know when you're ready.
Are you affiliated with ABRET?
No. CNIMExamPrep is an independent exam-prep company. ABRET and CNIM are trademarks of ABRET Neurodiagnostic Credentialing and Accreditation, used only to describe the exam we help you prepare for.
