Grades I - II / Class C Wastewater Exam Prep Study Guide (Free Lifetime Updates)

This study guide is for anybody preparing for their state's entry-level or second-level operator exam. It covers both exams in one volume, because the Grade II is defined as everything on the Grade I plus additional material, so there is no reason to buy two books. This was written for California, but only two of the fifteen modules are California-specific, so operators anywhere sitting an entry or intermediate exam, Class D, Class C, Grade 1, or Grade 2, will find the process fundamentals apply directly.

Forty-six lessons across 177 pages, built from CCR Title 23 §3701(c)(1) and §3701(c)(2), both of the State Water Board's exam information sheets, and fifteen years of running plants. Every lesson gives you the concept, the worked math, the operating logic, and exam-style practice questions with full answers, 325 of them. The weighting follows where these two exams actually concentrate: the math section and the independent 50% math gate that fails more candidates than anything else, stabilization ponds, preliminary and primary treatment, and safety. 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!
