Practise percentage, ratio, unit conversion and fictional medication maths questions, with worked solutions.
Practice only. Medication and infusion examples are fictional. Do not enter or rely on Xiliro for a real prescription, patient-specific dose, or clinical decision. Follow your local medicines policy and seek appropriate supervision when required.

What this result means
Each question is marked correct or incorrect against its own tolerance, with a worked solution available underneath.
Method
44 practice questions across 8 groups: percentages, ratios, unit conversion, and five groups of fictional tablet, liquid, mL/hour, drops/minute and error-spotting scenarios. Questions are picked at random from the group and difficulty you choose.
Assumptions and limitations
- Every scenario is fictional and for practice only — it is not a clinical decision-support tool and does not represent a real prescription, patient or dose.
- The score shown counts correct answers for this browser visit only; it is not saved, and it is not a competency or safety assessment.
