It is a weeding out process and an opportunity to learn from experience simultaneously. Outside of that, you can learn as much as you want, anyway you want. You wont hurt anyone.
Thank you. I tend to agree with you. And yet most or all of the people who installed the systems (I’m referring to steam systems in particular) that time and time again we see here (and in my own house) that are substandard or even ridiculous— all those guys made it through the weeding process. So how good is it?
Well, you have a point. But there are also doctors who just made C's. You don't want them working on you anymore than you want someone who squeaked by an HVAC/R certification process installing a steam system.
