"didnt start studying until three weeks out. the practice questions on permit application requirements for municipalities were what saved me honestly. passed but it was closer than id like to admit."

"i was pretty skeptical of exam prep sites in general but cpswqexam.com was worth trying. the bmp design questions were alot more nuanced than i expected on the actual exam, and drilling them here made that section feel manageable. the mistake review feature helped me stop second-guessing myself on hydrology calc stuff too."

"the full-length mock exams were the thing for me. got used to the pacing before the real test, which i definately needed. this site does a good job with stormwater pollutants and removal processes questions specifically."
