Extremely helpful I’ve taken the test once before getting this app and failed. This app has questions that are on the test. Thank u

It is a great app to study for 608 universal

Love it thank you for making this app

Would definitely recommend to any HVAC-R installer/Technician that is practicing for the EPA 608 Test!!

Haven’t tried premium yet but loving it so far.

Truly a great app! Read through the manual once, went through all the questions for all sections here once (core twice), got my universal license on first shot! Great design, great knowledge check and learning.

If you find yourself procrastinating book work but lose hours coding or gaming then this app is the way to binge HVAC Education!

Some confusing questions and equally confusing answers, don't waste your time and money on this. Not similar to real test. This person who created this application apparently has no idea about this certification.

Thank you for making this available
