Frequently asked questions
What is Quizzleaf?
Free medication math practice for nursing and pharmacy tech students. It covers all dosage math, not only IV drips. Dosage calculation practice gives you generated problems with worked solutions. Flashcards cover brand and generic names, drug classes, DEA schedules, federal controlled substance rules and sig codes. Teachers can create a class to see which flashcards each student knows.
Has a nurse or pharmacist reviewed this?
No. Problems and answers are computed and checked by software, and no nurse or pharmacist has reviewed them. This is practice only, not clinical guidance. Follow your instructor, your facility's policies and a current drug reference.
Where do the flashcard facts come from?
Brand names are confirmed in FDA's Drugs@FDA database or NDC Directory. Drug classes are FDA's Established Pharmacologic Class. DEA schedules must match the schedule on FDA's product listings. Law cards cite the Code of Federal Regulations or the US Code. Every card shows its source after you answer. The FDA data was retrieved 2026-10-25, and automated tests re-check the cards against it on every build.
Why does a class name look different from my textbook?
Drug class cards use FDA's official class names, for example "HMG-CoA Reductase Inhibitor" rather than "statin". Textbooks often use shorter names for the same class.
What counts as "mastered"?
A card is mastered after two correct answers in a row. A miss resets it. Missed cards come back within a few turns; mastered cards come back after a day, then three days, a week and three weeks.
Do I need an account?
No. Practice on your own is stored only in your browser. To join a class, a student enters the class code and a display name. Progress is tied to that browser, so a student who switches devices joins again and starts a fresh record.
What does it cost?
Nothing. Any future pricing will be announced in advance, and nothing is billed automatically.
Is there a paper version?
Yes, the Quizzleaf Workbooks, sold on Amazon: the Pharmacy Technician Math Workbook (also on Kindle) and the Nursing Dosage Calculations Workbook (also on Kindle). The practice on this site stays free.
I lost my instructor link. Can you recover it?
No. We store only a one-way hash of the instructor key, so nobody can look it up. Create a new class and share the new code. Bookmark the private link when you create a class.
Is Quizzleaf affiliated with PTCB, NHA, NCSBN, FDA or DEA?
No. Quizzleaf is an independent study tool. It uses public government data and contains no questions from any certification or licensing exam.
