HVAC practice test

Would be better if theyd tell you the right answer and why it is right not just that your wrong and heres the right one,i needa know why its right

Great app, though it needs more practice sections for things like static pressure and duct systems😴

I have taught college courses for an HVAC Apprenticeship and have learned from some of the Best, along with always considering myself to be an apprentice in the HVAC field that is ever changing. That being said, I was shocked at how many answers were searingly by the book with the author thinking of one possibility (typical of Mechanical Design Engineers with little hands on experience). There should have been collaboration with other experts before releasing such an error filled App. I will give credit for the discussion ability, but mostly novice learning are using this App, while I am on here searching for an App to help our Facilities HVAC Tech’s stay on top and to keep learning. Please revise all incorrect answers and get other insight, as we often need another persons perspective to get things right.
