Terms and refunds
Last updated October 24, 2026.
What you're buying
One payment gives you 180 days of access to the Class D Ready Class D practice course, starting at checkout.
Refunds
- Within 14 days of purchase: full refund for any reason. Email [email protected].
- Pass guarantee: answer at least 90% of the practice questions (water math excluded) and complete two timed practice exams before your exam date. If you don't pass the TCEQ Class D water operator exam, email us your result within 30 days of the exam for a full refund.
Not operating guidance
Class D Ready is for exam preparation only. It isn't legal advice or operating guidance. Rules change, so always follow your system's procedures and the current Texas Administrative Code. Class D Ready isn't affiliated with or endorsed by TCEQ, and our questions are not real exam questions.
Using the course
Your access is for you personally. Don't share your access link or copy the question bank.
