SkillCat has some good training on the app. Some of the more basic stuff is REALLY basic, but maybe some people need it. Working on my EPA Universal, finished my EPA Type 1. If I have a complaint, it's that after finishing a quiz, it doesn't automatically show your score...you must go back to the list of modules, click back onto the quiz before you can see your score. This app is good...and best of all, it is COMPLETELY FREE. Great resource for a new HVAC worker or one wanting to learn HVAC.

Overall, great app for EPA 608 Universal Certificate. Nothing beats free. Just a few issues with the app. Some questions on the quizzes get marked wrong when they are correct. Some questions are ambiguous. During the actual exam, I had several questions appear multiple times. Also, occasionally while navigating through the course, it would take quite a while for the menu to appear.

Excellent experience so far. I have made my way through a good portion of the lessons, and so far it has been really easy to navigate and breaks up lessons into practical application videos, repetitive examples to show new skills, and quizzes throughout to make sure you understand what you learned. Being able to do the lessons on my phone is a big deal too, I'm self employed, wich means my schedule is unpredictable, but I can work on this anytime, anywhere. Just perfect.
