Straight answers about what's included, how access works, and how this fits your CPSWQ prep.

Is this a subscription?
No. Every plan is a single one-time payment for a fixed access window - 48 hours, 7 days, or 6 weeks. There is no auto-renewal and no recurring billing.
Can I try it before paying?
Yes. You get 10 free sample questions with instant feedback - no credit card and no account required.
Are these real CPSWQ exam questions?
No - and that matters. These are original practice questions written to mirror the style, difficulty, and domain coverage of the CPSWQ exam blueprint. We never distribute actual exam content, so practicing here keeps you fully compliant with official exam policies.
Is this site affiliated with the official certifying body?
No. CPSWQ Exam Prep is an independent study resource for Certified Professional in Stormwater Quality (CPSWQ). It is not affiliated with, sponsored by, or endorsed by the official certifying body or exam administrator.

Feedback from people who used this platform to get exam-ready.
"I was nervous about the CPSWQ exam until I found this platform. The practice questions mirror the real exam style, and after five weeks of consistent prep, I passed on my first attempt with confidence."
"The analytics dashboard was a turning point for my CPSWQ prep. It showed I was weakest in Federal, State, and Local Regulations and Permit Application Requirements for Municipalities, Construction Activity, and Industrial Activity, so I spent my final two weeks targeting those areas. Smart studying beats more studying every time."
"Between work and family, I had limited study time for my CPSWQ exam. The structured plan kept me on track with focused 30-minute sessions, and the mistake review feature made sure I never repeated the same errors. Passed comfortably."
