FAQ
Questions students actually ask
How is this different from UWorld?
Answer
UWorld is a paid, polished question bank with a few thousand items and a tutoring layer baked in. NursingFloor is free, smaller (under a thousand active items right now), and brutally honest about which questions are verified to current standards and which are older or research-only. Use UWorld as your primary drill if you can afford it. Use us as your no-cost supplement and as a sanity check on the verification tier of any item you study.
What does 'Verified current' actually mean?
Answer
It means the question was drawn from a 2025 or 2026 source, then cross-checked against the current NCSBN test plan and current clinical references. If the answer rationale touches a value (drug dose, lab range, parameter), it's been checked against an authoritative reference. We never generate clinical values from a language model.
What's the difference between 'Verified only' and 'Everything'?
Answer
Verified only shows the post-NGN, fully checked core drill. Everything additionally includes older reference questions, research challenges with no provided answer (so you have to investigate yourself), and format-practice items. Start with Verified only. Use Everything once you want to push past it.
Are these actual NCLEX questions?
Answer
No. Real NCLEX questions are confidential to NCSBN and pirated dumps are unsafe and illegal. Every item here is written or adapted from licensed practice material and labeled with its verification tier. If you see a question elsewhere claiming to be the real exam, walk away.
Why don't some questions have an answer?
Answer
The challenge-and-research tier is questions where we have the prompt but no provided answer in the source. Treat those as research prompts: look up the topic in your text, your prep course, or NCSBN's plan, then write your own rationale. That work is half of how you actually learn the content.
