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 Yes a couple of the thousand questions are outdated but it still gives you all the information you would need previous to taking the epa 608 exam.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Outdated
Some of the questions are outdated.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Questions were almost identical to the actual, aside from the app being a little outdated in terms of design and functionality.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

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
