500 total practice items across all eleven domains, balanced to within one question of each other.
Domains independently mapped from NABP's publicly released NAPLEX Competency Statements onto eleven clinically organized study areas — verify current competency weighting against NABP's own materials before relying on it for study planning.
The real NAPLEX is a computerized adaptive test that draws items across competency areas dynamically based on your performance, rather than testing fixed named domains with their own timers. This portal instead lets you drill one domain at a time: pick a domain below and take a focused, timed testlet, paced at roughly the real exam's overall minutes-per-question. It won't feel like sitting the real adaptive exam, but it's built for honest, untimed-then-timed review of each domain.
The real NAPLEX converts your adaptive performance to a scaled score (0-150, passing at 75) using NABP's own proprietary conversion, which is not publicly reproducible — and 25 of the 225 real items are unscored pretest questions you can't identify while testing. This portal cannot recreate that conversion, so testlet results here report plain accuracy (percent correct) on a fixed testlet, with a study-signal label — not a scaled score of any kind.
