About these terms
These terms cover your use of the OperadorListo website, the free check, the free week and the monthly plan. By using the site or starting the free week, you agree to them. Based in Florida, USA. Contact: hola@operadorlisto.com. Mailing address: OperadorListo · 3000 Biscayne Blvd, Suite 210A PMB1086, Miami, FL 33137, USA.
What OperadorListo is (and isn’t)
- OperadorListo is practice software for the Texas Class D Water System Operator exam. OperadorListo is independent practice software. It is not affiliated with or endorsed by the Texas Commission on Environmental Quality (TCEQ). Our practice questions are original, written from public sources, and never copied from the exam.
- It is not a course, a class or a school: it gives no training hours, credit or certificate, and it doesn’t replace any training the licensing agency requires.
- Our practice questions are original. They are not exam questions, and we never ask you what was on your exam.
- It’s a study aid only. It isn’t advice for a real case, and it doesn’t replace the rules and publications of the people who give the exam, or a professional’s advice.
The free check
The free check is provided as is. Its score is a rough estimate from 10 practice questions, not a prediction of your exam result.
Free 7-day trial and monthly plan
- What it is: full access to OperadorListo, free for 7 days. Then the monthly plan: the same access, month by month.
- What’s included: practice questions by area with an explanation and a source for each one, timed practice exams, your progress by area and an AI tutor.
- Price: free for 7 days. You enter a card at checkout, and nothing is charged during those 7 days. When they end, we charge $29 automatically, and then $29 every month, until you cancel. We email you a reminder before the first charge, and one every year while you stay on the plan. In US dollars, plus any tax that applies. One free week per person.
- How to cancel: any time, with “Cancel or manage my payment” (Stripe’s page; the link is in your emails and in the app), or write to hola@operadorlisto.com and we cancel it the same day. Cancel before the 7 days end and you pay nothing. If you cancel after a charge, there are no more charges, and you keep your access until the end of the month you paid for.
- Refunds: full refund of the first $29 charge if you ask within 7 days of it, no reasons needed. Later monthly charges aren’t refunded; cancel any time so there are no more. See the refund policy.
The AI tutor
It’s software, not a person. It explains the question and our explanation. It can be wrong, so check the source it points to. It doesn’t give operating, dosing or safety instructions for a real plant, well, tank or distribution system (a real chlorine feed rate, a real sample result, what to do in a real emergency: the member asks their supervisor, their system's procedures or TCEQ); questions said to come from a real exam, or any help sharing or recalling exam content (TCEQ forbids it); a promise that the member will pass, or a question count or subject weight for the real exam (TCEQ does not publish them); legal advice about a license, a violation or an employer; and anything outside the TCEQ water operator exams. See the privacy policy for what we send to our AI provider.
Using your access
- Your access is for you. Please don’t share your sign-in links or account, and don’t resell or copy our content.
- Don’t post, share or ask for actual exam content. The exam’s rules for candidates forbid it, and so do we.
- We may suspend access that’s being misused.
Our content
The site, questions, explanations and software belong to OperadorListo. Other names belong to their owners.
Disclaimers
We work hard to keep every question accurate. If you spot an error, tell us at hola@operadorlisto.com and we’ll fix it. Even so, the site is provided “as is”. We don’t promise that you will pass the exam, or any exam result.
Limitation of liability
To the extent the law allows, our total liability for any claim about OperadorListo is limited to the amount you paid us in the 12 months before the claim.
Governing law
These terms are governed by the laws of the State of Florida, except where the law of your state says otherwise.
If you live in California
Under California Civil Code section 1789.3, you can reach the Complaint Assistance Unit of the Division of Consumer Services of the California Department of Consumer Affairs in writing at 1625 North Market Blvd., Suite N 112, Sacramento, CA 95834, or by phone at (800) 952-5210. The price and how to cancel are above, under “Free 7-day trial and monthly plan”.
The numbers in the practice
OperadorListo’s questions, math problems and explanations are for studying for the exam. The numbers are practice numbers. They are not instructions to operate, dose or check a real plant, well, tank or distribution system. For that, follow your system’s procedures, your supervisor and TCEQ’s rules.
Price changes and changes to these terms
- If the price changes: we email you 7 to 30 days before, with the new price, the day it starts and how to cancel. Cancel before that day and you are never charged the new price.
- If these terms change in a way that affects your plan, we email you first, with how to cancel. The date of the latest version is at the top.
