User reviews

EPA

Great help getting ready for EPA 608 ended up getting my universal certification. Definitely a big help.

Best 608 test.

I used this to study for my 608 test. The questions and the answers are word for word what I seen on the test. I used this for about two weeks before taking my test and got it on the first try. I also do not leave reviews often. But I felt that this one deserved it.

Yes

Great practice test yes the questions are repetitive but gives you same perspective as what your gonna see on the test

As good as it gets

Obviously any app is gonna have its issues. Yes a couple of the thousand questions are outdated but it still gives you all the information you would need previous to taking the epa 608 exam. The app has multiple different options and levels for review and helps you out when there’s certain questions you have a lot of trouble with.

Not conducive

The way the app was allowed for me to see the whole bank and retest as necessary the new bank is 3x as long and doesn’t allow me to view all questions once …. The update is counter productive.
