thanks guys, I realise I'm not allowed the actual questions but just left a bit curious as to what this difference was. The tester did give me the idea that the twin who scored highest actually started with a few 0's but then progressed but the other started well and then bombed (and I would say the one with the highest score has the best comprehension). Are you allowed to make up a similar type of question (one that is not on the test at all) to give me an idea of what sort of comprehension we are talking about in the top half of the 6yr old range. I guess I just have no idea whether they were asked about general knowledge, or read a passage and asked to interpret it or what it was all was like. I do understand that you may all not answer my question as it is inappropriate but if there is anything you are allowed to say to give me a general idea that would be great (certainly don't want anyone to break any rules)
