I just from exam. I don't know, about the results, but those questions suck. Today I tried it second time. What can I say, there are a lot of questions of air conditioning systems, ducts, chimneys installations, flashings and also math tasks with formulas. Actually, it looks that they give less time for answers, than those questions require. You can't think a lot, just like robot to go throw it quickly. It's stupid. Too many questions.
