Operator Master

Operator Master helps water and wastewater operators get ready for their certification exams. • Answer Questions: mixed practice questions with a clear explanation after each answer. • Math: wastewater calculations broken into steps, one skill at a time. • Practice test: a timed, exam-style test that hides help until you finish. • Ask Klok: missed a question? Tap Klok for an explanation, or ask him about a process, a piece of equipment or a math problem. Sign-in required; 5 free answers. • Short lessons, glossary terms and pictures, formula help, and a free math course. • Daily goal and streak to keep you studying. • Works without an account; sign in with Apple or Google to save progress across devices. Premium (optional subscription) adds a study plan built around your test date, the ready check, the 30-minute cram on your weak spots and more. Choose Premium Monthly, Premium Yearly, or Course Pass + Premium (Premium plus every course for credit, taken on operatormaster.com). Subscriptions renew automatically until cancelled in your Apple Account settings. Levels follow the state you choose.
