NHA ExCPT / CPhT Prep. The ExCPT is a dispensing and pharmacy-math test, not a top-200 drug-name quiz. Dispensing Process is 43 of 100 - intake and order entry, days-supply, dilution and alligation, compounding - drilled until the math stops scaring you, every card spoken aloud. DEA schedules and tech-vs-pharmacist scope, exact. Scaled 390 is the number. 100-question practice bank, every fact taught aloud with a memory hook, explained answers, review tests at the real passing bar. Your first module is free — no card required.
