Yes - the bank is maintained against the current exam outline, and questions are revised when the exam changes.
No honest practice platform can guarantee a pass. What realistic practice does is show you - before exam day - exactly which domains are weak, and give you the repetitions to fix them. That's the difference between hoping you're ready and knowing where you stand.
Yes. You get 10 free sample questions with instant feedback - no credit card and no account required.
The free sample shows you the question quality. Paid plans unlock the full 1,000+ question bank, exam-style practice modes, mistake review, and - on Fast Track and Pass Confidence - progress analytics that show your readiness by domain.
No. Every plan is a single one-time payment for a fixed access window - 48 hours, 7 days, or 6 weeks. There is no auto-renewal and no recurring billing.

For most countries, the price you see is exactly what you pay - tax is already included. Where local law requires it to be added separately, it's shown clearly at checkout before you pay, so there are never any surprise fees.
Access is instant after payment and runs for your plan's full window from that moment. When the window ends, your local progress stays on your device - you can buy another window any time and pick up where you left off.
Yes - the whole platform is mobile-first: practice, mistake review, and analytics all work on any phone, tablet, or laptop with a browser. Nothing to install.
Every answer feeds your per-domain accuracy, readiness score, and weak-area list. Instead of re-reading everything, you drill the domains that are actually costing you points - that's what moves a score in days, not months.

Real feedback from CEU candidates on Reddit.
"put this off for months then had like three weeks before my exam date. the Q513 steam plant questions saved me, i hadnt touched a boiler since cadet days. grinded practice sets every night and somehow passed first try."
"wasnt sure the online stuff would actually match what NMC asks but it was close enough to not matter. the mistake review feature is what did it for me, kept missing the same governor questions until i actually understood why instead of just memorizing answers."
"ceuexam.com got me thru the management level stuff, especially the crisis management and casualty control questions which i was definately weak on. did the mock exams on repeat for like a month. relief more than anything when the results came back."
