Just doing this test now sorry for the gravedig of a 9 month old post!
but yes I failed it as well.
In terms of what the course offers you I think people shouldn't stress so much. Even if you did a course in a college you wouldn't have the experience required and would need to develop that with someone.
I know because I'm already a time served plasterer, I was fecking useless out of college. As a plasterer btw pay attention to how you site your boxes...there is a reason all spreads hate sparks
Even so I won't be finishing this course and attempting a rewire solo, even though I've been around rewires already many many times through my day to day renovation work and I pay a lot of attention and ask a lot of questions. Experience is everything, college is only ever to get you started whether distance learning or normal.
I remember one nice old timer giving me a test after I'd literally just finished a small test on the topic. He pointed to some plugs spurred off a ring final and said "go on whats wrong with that" and my mind went blank, couldn't see it, couldn't think of it. Came up with all kinds of crazy ideas. It was 3 plugs off one spur. Of course it was wrong, but I couldn't see it. Lack of experience. He says "now I"m ripping all this out so it doesn't matter but if you went to a customers house to do a minor repair or fix a problem you'd have missed that, but you'd still be responsible for it once you'd done some work on that circuit"
Or something along those lines, this was early last year, works been busy so I had to put the books down for a while. Just doing a house renovation after a family member died (inheritance) and I wish I was further along as I've got a spark delaying us by not finishing the first fix, and its super annoying. Can't finish boarding, don't want to start plastering until I have...got floorboards up everywhere that I keep falling over....sigh so books are open again.
