I did not realize that once you say “I know” you can’t access the question again. Im bummed I paid the most I have paid for an app and I can’t access what I feel I paid for. It wish I could enlarge the math description to get to the answer but there isn’t that ability and the formula is very small. ### 5/5 — Study anywhere *2025-07-26, version 8.99.10566* This app is great. ### 3/5 — No Explanations *2025-02-21, version 8.99.10566* Does not explain anything about the answers to the questions just tell you if they are right or wrong ### 5/5 — Price hurts but… *2025-02-07, version 8.99.10566* I passed my Ohio class 3 water supply using this app. All the info that you can get through other classes was useless, this was the only reason why I passed! ### 3/5 — Price hike without quality to back it *2024-05-29, version 8.99.10566* The price of this service increased 50% on top of becoming a quarterly subscription rather than yearly or lifetime. On I’m ready to pay a premium price for a premium product but there are several things missing: many questions that are either not correct or have synonymous answers. Also there aren’t explanations for all the questions just randomly or only the math ones . It’s still the r best tool on the market (app wise) but the cost isn’t justified. ### 1/5 — Not enough *2024-01-17, version 8.99.10566* Not enough on waste water treatment ### 1/5 — No good *2024-01-04, version 8.99.10566* None of the questions are actually on the test or useful for studying for the test ### 3/5 — An explanation please! *2023-10-04, version 8.99.10566* Correct or incorrect, It would be beneficial to have an explanation of the question and answer, like with the math questions. ### 1/5 — Bad!!! *2023-08-27, version 8.99.10566* Most answers are wrong!!!! I don’t understand why the app get 4.6 stars while all the reviews are one or two stars. $30 for 6 months, trust me, buy something else. Reduce rating from 2 to 1 star. I can give it minus 5 stars if I could!!!!! The more I go through the more wrong answers they are. I have reported a bunch of them, no improvement!!!! ## Frequently asked questions about AWWA Opcert Exam Prep ### What does the AWWA Opcert Exam Prep app do?
