  • ★★★★★F$?& U HULU

    Yes

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

  • ★★★★★BrycenP2025

    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 Yes a couple of the thousand questions are outdated but it still gives you all the information you would need previous to taking the epa 608 exam.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.

  • ★★★★EPA student2026

    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.

  • ★★★★agelito✌🏻

    Restore the old version

    Now there’s more questions that not appear in the real test

  • ★★★★Kingkp35

    Bad timing for a change

    I think y’all should ho back to the original way it looked with CORE having only 224 questions there to many questions in the way or make a mode for only the 224 plz and thank you

  • ★★★★★canadex

    Outdated

    Some of the questions are outdated. The use of CFC R-13 and R-503 are no longer used . So if this type of question is in the exam this will confuse anyone.

  • ★★★★★Ggotissues

    Worth it!

    Questions were almost identical to the actual, aside from the app being a little outdated in terms of design and functionality. It is great and worth the $10

  • ★★★★★77IsaacP

    Solid app

    If you want to pass the test review this passed it first time

  • ★★★★0187&319

    App is poorly designed

    I have been trying to study for this test and everytime I move my phone ends up rotating the screen causing the entire app to stop working and be in disarray allowing me to never finish a full test knowing what I missed

  • ★★★★★ElGallo07

    Helped me pass

    Failed my epa 608 universal 2 times, I decided to buy this app to help me study. This app pretty much has most of the questions on the test. Just passed with a 70% just now! This app saved me
