Question 1

Do these questions come from the real exam?

Accepted Answer

No. Certification exams are secured and their questions are confidential. Our questions are written from the published exam outline and the same reference material the exam is drawn from, so the topics, weighting, and difficulty match what you will face.

Question 2

How much does it cost?

Accepted Answer

Nothing. Study for Water is 100% free for water and wastewater operators — every course, question bank, math drill, and timed practice exam. There is no card required and no trial limit.

Question 3

What is the diagnostic assessment?

Accepted Answer

A short mixed quiz you take before studying. It scores each topic separately and turns those scores into a recommended study order, so you start with your weakest weighted topics instead of page one.

Question 4

What is the difference between study mode and test mode?

Accepted Answer

Study mode shows whether you were right and the explanation immediately after each question. Test mode withholds everything until you submit, which is closer to exam conditions and better for measuring readiness.

Question 5

How do the math drills work?

Accepted Answer

Each drill generates fresh numbers every time from a formula template — pipe volume, dosage, detention time, flow and velocity, pressure and head. You enter a numeric answer and it is graded with a small tolerance, then you see the worked steps.

Question 6

Is the practice exam timed like the real one?

Accepted Answer

Yes. It uses your course's question count and time limit, draws questions weighted by topic like the real exam, counts down, and auto-submits when time expires. You get a scored review afterward.

Question 7

Can my utility add the whole crew?

Accepted Answer

Yes, at no cost. A department manager account can add staff, see each person's readiness and last activity, and export progress and exam history to CSV for training records.

Question 8

Does it work on a phone with spotty service?

Accepted Answer

The app is built mobile-first for one-handed use. You do need a connection to load and save a session, so we keep sessions short and save your progress as you answer.

Question 9

My course is not listed. Can you add it?

Accepted Answer

Often, yes. Tell us the section — Water Treatment, Wastewater Treatment, Water Distribution, or Wastewater Collections — and your license level through the contact form, and we will tell you where it sits on the roadmap.
