## Description

Three full exam decks — Yellow, Green, Black — 300 original questions, and every single answer explains itself. Prep that teaches, not just tests.

Most exam apps test you. BeltUp teaches you.

Three hundred original questions across three full belt decks — and every one carries a plain-language explanation written from twenty-seven years of real deployments at the sharp end of industry, not from a textbook index.

YELLOW — 100 foundations: the wastes, takt, 5S, DMAIC, the daily huddle, the language of improvement.
GREEN — 100 practitioner: capability, hypothesis tests, measurement systems, pull-system design, the numbers behind the method.
BLACK — 100 advanced: design of experiments, advanced SPC, non-parametrics, and leading a transformation that survives its leader.

— Shuffled decks, 70% pass mark, exam-style scoring
— Every answer explained — the explanation is the product
— Worked calculations with real factory numbers
— Offline, no account, no tracking

Whether you sit a certification next month or lead a programme next year: this is the bank that makes the knowledge stick.
