Just took the aptitude test for local 440

When and where will I receive the test results. I know it takes 72 hours to get them but from where. Also I have been doing plumbing everyday full time from 14 yo because I had to grow up quick. Now 19 and am trying to get into 440 I have a lot of knowledge of different types of work. plumbing is all I know does anyone think that I’ll definitely score high in an interview if I get on the list?
