Mock exams
Sit the exam before you sit the exam.
Train across the official 85–150 item range and five-hour window with Koydo's CAT-style engine, then review your practice signal and on-screen explanations. This is exam-shaped practice, not the official NCSBN scoring engine.
Available during the 7-day no-card account window.

How a mock run works
- 1
Start with the published constraints
The timer and 85–150 item range let you rehearse pacing and stamina on phone or desktop.
- 2
The practice engine adapts
Every answer updates Koydo's estimate and steers the next item. NGN case studies use partial-credit practice scoring.
- 3
Review the evidence
Finish with a directional practice signal and a miss-by-miss review using the available on-screen explanations.
Built like the real thing
Published length and pacing
Practice can extend from 85 to 150 questions inside a five-hour window, matching the official range rather than the official scoring engine.
Honest readiness signal
You finish with a practice signal grounded in your accuracy — never a fake “you'll pass” promise.
On-screen rationale review
Review every miss with the available written explanation and save questions for later practice.
NGN partial credit
Case studies score every correct clinical decision, matching the 2023+ Next-Generation format.

Mock-exam questions, answered
How many questions is a mock?
The Koydo session runs between the NCLEX-RN's published 85-item minimum and 150-item maximum, using Koydo practice rules rather than NCSBN's proprietary scoring engine.
Does it predict whether I'll pass?
No, and we won't pretend it does. It produces an uncalibrated practice signal from your real accuracy — a study compass, not an official score.
Can I pause a mock?
Yes. Your session state is saved — though we recommend at least one uninterrupted full run before test day.
Are NGN items included?
Yes — full case studies, bow-ties, matrix, cloze, highlight and ordering items, scored with partial credit.
