As a supplemental study material to the books, this app is great! There are hundreds of unique questions to test yourself on, and you can do a little bit every day. However, it is very inconsistent with its math questions. Often, the answers to the questions asked expect you to round your numbers, with no indication that they expect you to do so, or by how much. It is immensely frustrating. Still, the app helped me pass my Class 2 Water Supply Exam, and I intend to use again for my Class 3!

Wouldn't recommend. Just sat for my grade 2 WT exam (passed) and literally none of the study material through the app was on the test. The only good that came from it was being able to make an "educated" guess on maybe 5 question.

Purchased moduals prior to the app update, spent about $60+ on all water treatment. After the update, i am now being forced to spend another $60+ for the same modules on a subscription basis AND the questions don't even rotate. They're all the same. I hate the new update. If I've already paid for full access why should I be forced to pay for it again.
