Certification Core

Four rings — Core, Type I, Type II, Type III. Each ring lights as your rolling accuracy on that section climbs. All four at 70%+ = Universal ready.

Build a Practice Set

Practice mode shows the correct answer and the regulation behind it after every question, and it never counts against a mock-exam score.

Topic Drills

Universal Mock Exam

Mirrors the real thing: 100 questions — 25 Core + 25 Type I + 25 Type II + 25 Type III, no feedback until you finish, and each section is scored separately. You must clear 70% on all four to earn Universal — clear only some and you keep those and retest the rest.

Timer runs but never cuts you off — the real exam is generally untimed or generously timed. Aim for under 90 seconds a question.
