Pharmacy calculations practice, one skill per page: conversions, ratio and proportion, dosing by weight, days' supply for tablets, liquids, inhalers and insulin, concentrations and percentages, dilutions, IV flow rates and business math, each with worked examples and practice problems with full solutions.

Prescription interpretation, one page at a time: the parts of a prescription, sig codes for routes, times and dosage forms, writing the label in plain English, error-prone abbreviations to avoid, look-alike sound-alike drugs and practice prescriptions.

Third-party billing for pharmacy technicians, one page at a time: reading an insurance card, how a claim is processed, copays and deductibles, the most common rejections and how to fix them, prior authorizations, formularies, Medicare and Medicaid basics, and coupons.
