FAQ
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%.
Can I get a refund if I change my mind?
No. 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%.
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.
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.
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.
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.
Does one plan cover every exam?
CNIMExamPrep covers one exam, the ABRET CNIM, so one Premium subscription unlocks everything on the site. Premium is per exam on all our sites, and you pick the exam at checkout.
What does Premium include?
Everything for the exam you choose, for as long as your subscription is active: the question bank, timed simulations, study notes, flashcards with spaced repetition, mind maps, video lessons as they release, your mistakes bank, detailed reports, the Readiness Score, all 5 bonuses and the Pass Guarantee.
How does the Pass Guarantee work?
Complete the full prep for your exam: answer every question in the bank, read every study topic, finish 2 timed simulations with your latest at or above the pass mark, and reach a Readiness Score of 80. Then sit your exam within 60 days while your access is active. If you don't pass, email us your official result notice within 30 days and we refund 100% of what you paid. Your dashboard tracks every requirement live.
What's the Readiness Score?
A 0 to 100 score on your dashboard that combines your accuracy, how much of the bank you've covered, your timed simulation results and your flashcard mastery. Reaching 80 takes consistent above-pass-mark work across the whole bank, which is why it is the bar for our guarantee.
What do I get with a free account?
Your saved free-test results, a starter Readiness Score, the first study-notes topic and flashcards for every exam, the mind map outline, your mistakes bank and the IONM Values & Alarm Criteria Sheet. Upgrade any time to unlock the exam you're taking.
Is it a subscription?
Yes. Premium is $147 a month per exam (about $4.83 a day) and renews monthly until you cancel. You can cancel in two clicks from your account, and there's no minimum term. 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.
Can I get free access by referring friends?
Yes. Every account, including free ones, gets a personal referral link in the dashboard. Share it anywhere. Each person who signs up through your link and buys a plan earns you a referral ticket, and each ticket unlocks any exam of your choice for 14 days.
Can my employer pay?
Yes. Many hospitals and neuromonitoring companies pay for CNIM preparation. Check out with your work email and we'll send a receipt you can expense.
Can I study on my phone?
Yes. Everything works on phone, tablet and computer, and your progress syncs to your account.
