FAQ
Questions students actually ask
What does 'Cross-checked' mean on a card?
Answer
It means a second pair of eyes verified the term and definition match an authoritative source (a current text, a peer-reviewed reference, or an FDA label). Cards without the badge are still drawn from licensed material but we haven't done the second pass yet. Treat them as study pointers, not gospel.
Should I use Browse mode or Study mode?
Answer
Browse mode is for scanning, search, and finding a specific card. Study mode is for active recall: it shows one card at a time, you try to answer before flipping, and you mark it as known. For real learning, use Study mode. For reference, use Browse.
Does 'mark as known' help me long-term?
Answer
It hides cards you've internalized so you can focus on what's still shaky. Your marks save to your account and persist across devices once you sign up. We don't do full spaced repetition yet, but that's on the roadmap.
Can I export to Anki?
Answer
Not yet. Anki is the canonical spaced-repetition tool and a lot of nursing students live in it. We'd rather build a clean export than a half-working one, so it's planned but not built. Email us at support@nursingfloor.com if it would unblock you and we'll bump priority.
Why do some cards skip the verification badge?
Answer
We label every card with how far we've checked it so you can decide how much weight to give it. If a card has no verification badge, it was extracted but hasn't been cross-checked yet. We surface it anyway because most of it is still useful, and hiding incomplete work would be dishonest.
