Jack's mum, when researching some months ago, the various research articles I found on the ravens matrices which showed a few images of the questions did seems to be the same test. The children's version I found images of was also the same but with parts of question coloured, this is definitely not just a b&w copy of the children's one though as that is much shorter. There are a few different versions though I believe, so it is entirely possible that your son did a different one and the link provided is still legitimate. Or it might not be. The Internet is obviously not going to be a definitive source of iq testing.
