Grade III / Class B Wastewater Exam Study Guide (Free Lifetime Updates)

This study guide is for anybody preparing for their state's journey level exam. This was written for California, but only two of the fourteen modules are California-specific, so operators anywhere sitting an intermediate-level exam, Class B, Grade II, or Grade III, will find the process fundamentals apply directly.

Fifty-four lessons across 165 pages, built from CCR Title 23 §3701(c)(3), the State Water Board's Grade III exam information sheet, and fifteen years of running plants. Every lesson gives you the concept, the worked math, the troubleshooting logic, and exam-style practice questions with full answers, weighted toward where the exam actually concentrates: activated sludge process control, nitrification, and solids handling. Twenty-three lessons include a QR code linking straight to the video where I work the problem or walk the process at my plant.

Anybody who purchases this guide will get future versions for free! Future versions will have updated QR codes when new videos are released and any corrections, edits, or regulatory updates. Happy studying!
