Texas Water Operator Class B Exam Prep

Current Status

500 original practice questions across 9 subject areas, organized on the subject areas TCEQ publishes in its Need-to-Know guidance for Class B operators — one program serving all three Class B specialties, with specialty-tagged questions (255 common, 90 Groundwater, 90 Surface Water, 65 Distribution).
Practice for a computer-based exam: the full practice exam runs on the same 3-hour limit TCEQ publishes for the real CBT sitting.
A free 12-question sample exam with a fixed set, so you can gauge the style before you buy.
A full 100-question practice exam (180-minute clock) drawing fresh questions on every attempt — the 100-question draw is this program’s own practice format.
Calculation items throughout — 60 across the bank, all in the Math area — dosage, detention time, filtration rates, well levels, and disinfection CT worked from standard conversion constants.
Our practice exam is scored against a 70% practice benchmark, set to mirror the published 70% passing standard TCEQ publishes for the Texas water operator exams. PRACTICE BENCHMARK ONLY — your score here is a study signal, not a result on the real exam.
