About this app

Prepare for your NCCCO Certified Crane Operator exam with confidence. CCO Prep gives you the study tools, practice questions, and realistic exam simulations you need to pass — all in one app.

500+ PRACTICE QUESTIONS
Cover every exam topic with over 500 questions across 9 categories including Core, TSS, TLL, LAT, SVC, SGP, Rigging I, Rigging II, and Swing Cab. Each question includes a detailed explanation so you understand the why, not just the answer.

SMART STUDY MODES
- Practice Mode: Focuses on your weakest areas first using spaced repetition, so you spend time where it matters most.
- Study Mode: Work through questions in order for structured, sequential learning.
- Review Mode: Targets your most-missed questions to shore up problem areas before exam day.

REALISTIC EXAM SIMULATIONS
Take full-length practice exams that mirror the real test — no instant feedback, a running timer, and the same 75% pass threshold. Customize exam length or go full-length for each topic. Resume incomplete exams anytime.

TRACK YOUR PROGRESS
See your full exam history, average scores, and per-question performance at a glance. Review past exams question-by-question to understand exactly where you went wrong and what you got right.

STUDY ANYWHERE
CCO Prep works offline. Your progress, scores, and study data are saved locally so you can study on the jobsite, on the road, or anywhere without a signal.

Whether you're a first-time candidate or recertifying, CCO Prep is the most effective way to prepare for your crane operator certification exam.
